    Genetic questions!

    I agree! It's great fun!

    Genetic questions!

    I don't know for sure. Understanding the genetics (as written in books and webpages and modeled by the calculator) seems to be much easier than seeing how they apply to real chickens, especially when they are mixes of mixes!

    Just had first hatch, trying to figure out genetics for crosses

    Assuming you are using this calculator: https://kippenjungle.nl/chickencalculator.html Or one of the other variations on the same site. When you cross a gold chicken with a silver chicken, no matter which direction you do the cross, you can get sons with one gold gene and one silver gene. When...

    Genetic questions!

    Accuracy is probably around 9 or 10 for some things (Extended Black is dominant over Partridge, Silver is dominant over gold, percent of offspring with certain gene combinations when crossing certain parents.) Accuracy is much lower for some kinds of details (picture shows a chicken with...

    Just had first hatch, trying to figure out genetics for crosses

    Silver Phoenix rooster with Crested Cream Legbar hen should be a barred/not-barred sexlink (sons get barring from their Legbar mother, daughters do not have any barring.) But with the other colors and patterns involved, I don't know how obvious the barring will be. I think it would be most...

    Black sex link with pea comb?

    Dominiques have rose combs. Your chick has a pea comb. The two comb types are caused by different genes. So no, the hatchery could not have produced this chick by using a Dominique instead of a Barred Rock. Given that the chick has a pea comb, I think it is likely to be an Olive Egger. Many...

    Do Chicks Care About Calcium? Or is it about companies and outdated studies

    If I remember correctly what I've read about excess calcium, different chickens show different levels of problems, even when they are all eating the same food and all the same breed. So a high-calcium environment could just select in the direction of higher tolerance. The least tolerant ones...

    Feeding a little of everything

    I wonder if you can make a spot that the geese can reach their heads in to eat, without having to put their whole body in? They do have pretty long necks.

    do i still need predator-proofing ? (for a rooftop)

    Are people allowed to go on the rooftop and do things there? Some buildings have flat roofs, and the roof is usable space (helicopter pad of a hospital, swimming pool of a hotel, place with benches and potted plants where apartment dwellers can spend time, something like that.) It might be fine...

    Thoughts on breeds?

    You might try this: https://kippenjungle.nl/sellers/page0.html That has links to several pages. Page 1 is basic genetics (if you're good on guinea pig genetics, you can probably skip that one.) Page 2 talks about chicken genetics, including discussions of specific genes and what they do. Page 3...

    Heat packs good emergency warmer when heat lamp bulb bursts?

    I would buy two heat lamp bulbs right now, so you have one and a spare. Have you looked for any other bulbs in your house that produce heat and could be put in the heat lamp? Check by holding your hand near a bulb to see how much heat it makes. In general, incandescent light bulbs will produce...

    Is this diet balanced?

    The usual solution to that problem is to feed it wet. Either a wet mash (get it wet and give it to the chickens), or actually fermenting it. When it's all wet, the powder stays stuck to the feed, and the chickens eat it too. I would not pay extra for a feed of that type (as compared with...

    14 dead chicks found in coop!

    That is the main thing I can think of, too. 300 chicks can be pretty heavy if they pile up, and that can be pretty hard on the ones at the bottom. Just a guess, but maybe the biggest chicks ran fastest or pushed through the rest, so they got there first, so they ended up on the bottom of the...

    Is this diet balanced?

    If they have a major nutritional lack, they might leave the fermented scratch grain and eat more of the grower crumble. But the chickens might eat until they have enough calories (mostly from scratch), and then realize they need more of something (example: protein) so they go eat grower crumble...

    Training Chickens For Extensive Handling - Resources?

    In that case, I would not bother trying to take a chicken away from the flock for training, if you just want it to accept handling, and don't actually care what the chicken is focusing on.

    Training Chickens For Extensive Handling - Resources?

    In my experience, chickens get used to anything that happens regularly. So I would just pick each one up, gently go through as much as you can of the things you want to do, then put the chicken down. Pick up the next chicken... If you have enough time to do each one every day, or even twice a...

    Duck incubation questions: lockdown, humidity and what happens if they hatch and I’m not there?

    If they are going to hatch at all, I think they will probably do it by Monday. So I would probably leave them until then. If they are already dead, you could peel the shell off and it would not change anything. That would satisfy your curiosity about their condition, and you would not spend the...

    Sex links?

    Recessive white would turn all colors to white, so the chick would not show that much color. Putting that with how many chicks are dark vs. light, I'm pretty sure recessive white is not causing the light chicks. So the white comes from Dominant White turning the black into white. And then both...

    Rooster cant shoot directly inside hens cloaca

    Probably yes. And they might be fertile into the next week as well.
