The eggs in my incubator have been hatching since late last night. I have three broody hens that have been sitting for awhile, one has been sitting about 4 weeks. My plan is to put the chicks in with her. She is in the coop now, and I know I should have separated her already into the tractor but it's been really cold the last two nights. Is it too late for me to move her now if I want to make the switcharoo tomorrow night? Is it better if I put them with her in the coop and move them all the next day?
