so just did a little research on my own question and found out that:
Fresh eggs have to be cracked to determine if they are fertile
Candling can be done after 5 or more days of incubation
If you have a rooster with the hens and their cracked eggs are fertile you can assume that at least some of the other ones are too but there is no way to know for sure w/o candling or cracking.
So, here is the plan please tell me if it makes sense:
Starting in February of next year I will leave fake eggs in a nest in hopes one of my hens will go broody
When/if she does I will check a few cracked eggs to see if they are fertile then I will collect them for a few days and stick them or other hatching eggs under her.
Then I will wait till dark and move her to the broody pen and hope that everything goes as hoped for/ expected from there.
If I am missing something please steer me in the right direction. Thanks!
You do not have to crack eggs to determine if they are fertile. If you have a rooster and he is mating with your hens, your eggs are fertile. I would set them under the broody and candle on day 7 after they've been nder her. If they were not fertile they will be clear. Take those eggs and cook them for the dog or chickens. If they have any darkness inside, they are growing.
I have put eggs under my broody that were gathered and put in an egg carton on my kitchen countertop. I figured they weren't fertile since I only saw the rooster mount her one time. So I took 5 of the eggs as an experiment and put them undermy broody. Well from the five eggs I got four chicks. The rooster is busier then you might think. And if they've mated at any point in the last 30 days the eggs will be fertilized.
