Crowing
Oh and if you get a rooster and decide to hatch chicks to increase your flock, you have to be prepared for at least half of them to come out roosters. If you are ok dispatching the ones you don't want for a chicken dinner that's ok but if you think you might have a problem with doing that, hatching chicks might not be for you. Rehoming unwanted roosters can be tough and it is never ok to just release them into the wild. Not saying you would, just a general statement.Production red and barred rock are very high producing breeds that are pretty easy to get along with so good choice for getting eggs. They also do ok in hot or cold. When it's hot just put ice or a frozen pop bottle full of water in their waterer and make sure they have shade available. It should never get cold enough in TX for you to have to worry about them as long as they have a dry shelter to roost in and keep the wind out.
Any breed like production reds that are bred specifically to lay a lot of eggs will usually drastically reduce their egg production around 2 1/2 or 3 years and can be prone to egg binding in later life but that depends on the breeding stock used. It's not a guarantee that will happen.
You can transition them when they have lost all their fuzz and have full feathering as long as it's not super freezing cold. If you live in texas by the time they get their feathers it should be ok to put them out.
If you get any guineas I just hope you don't have any neighbors nearby that mind noise. They are extremely loud and noisy.
Problem with getting a rooster is you can never tell what they will be like until they mature. Honestly the main purpose of a rooster is to make chicks and distract whatever predator is threatening long enough for his hens to get away and take cover. I know there are videos of roosters driving off predators sometimes and it happens but I wouldn't count on that. Often the ones aggressive enough to do that are also human aggressive so you have to manage expectations there.
I've seen my chickens avoid bees so I think they know they're not good to eat.
The most wary breed I've encountered is leghorns. They are extremely flighty and they do lay a lot of eggs. White ones lay the best but white chickens are more easily seen by predators so brown leghorns probably better.
Good luck with your new chickens!
