I've been questioning the hand-turning factor myself. The one good hatch I had last year (17 of 21) were hand-turned for the first couple weeks. I just can't identify why exactly this would make so much difference. I thought it seemed logical that maybe the eggs did better lying on their side...
Year 2 of call ducks: hatch rates are even worse, basically nothing!
Between the few I hatched last year and the ones I purchased, I am now setting call eggs from my own small flock. They free-range all day and are decent egg layers so far.
Since the beginning of March I have incubated 72 call...
Update to this discussion.
I did a 100% dry hatch with 21 call duck eggs, averaging 25-30% humidity throughout incubation.
For the first 2 weeks or so, I kept them on their sides and hand-turned. For the last 10 days, they were upright in the auto-turner.
18 made it to lockdown.
Of those, 17...
Okay, that makes sense. So maybe what I need to do is keep closer tabs on air cell size throughout incubation for the next batch in hopes of figuring out my ideal humidity for call ducks.
I just had a great chick hatch, 13 out of 16.
I'll try some runner ducks next month and how they go...
Sorry, to clarify, you had mentioned having all of your mama duck's ducklings dying after a successful hatch. I just meant I haven't experienced that problem. Only deaths in the egg.
Hey I did I read your humidity article a while back! I'm sure many others have appreciated that resource! Thanks for taking the time to make that.
Why do you say 45% would be too high for your ducklings?
At 99 F, wouldn't your 45% RH be the same as my 45% RH?
You would just have to add less...
Thanks for your thoughts!
Do you dry hatch?
I have 8 more on day 18. They had been at 45-50% humidity like the others, but bator ran dry a couple days ago. I haven't refilled the water yet. After my first round, now I'm wondering if I should leave it at 29% for this last week of incubation...
I wonder if your hatch is just going to start later.
I get concerned when there's plenty of hatching action in a bunch of eggs but the other eggs are doing nothing.
Yours sound like they may just be getting started!
Have you hatched call ducks with success in the past?
Opened the 5 eggs that didn't hatch and still not sure why they didn't hatch. Yolk partially or not absorbed, none internally pipped, some weren't quite in hatching position yet so probably died prior to day 25.
Wouldn't say they were too fluid-y, but definitely a thin layer of slippery...
This is my first real attempt with call ducks.
For this batch I had 12 eggs start. 45-50% humidity, temp consistent 99.5, in an auto-turner.
10/12 made it to day 23. All looked great with movement, veins, and good air cells. Moved them to my hatcher with 65-70% humidity.
I had 5 pipped by...
Thank you, I'll look into Ectiban a bit more. I'm sure this would be a multi-application product but it's worth looking into.
Thank you @iwltfum. I don't have the experience with agricultural products that you would have, but my understanding is that spinosad is NOT systemic. It can only...
I'm interested in using it as a one-application product for external poultry parasites. Where did you read about it being toxic to mammals? Everything I've read has suggested the opposite. It is used in flea products for dogs.
I don't doubt that it isn't officially approved for use on...
Thanks! Do you remember the name of the spinosad product you saw at Peaveymart? Was it a gardening spray?
Our local agri store doesn't carry any type of spinosad product as far as I know. If it could be acquired through a licensed individual (vet etc) in Ontario I would be interested in...
