I'm back here for some more advice. Sorry about the long post.
After yearning for more broody hens, I got my wish. Now I have my hands full! I'm on my 4th broody this year. The first one I expected -- she has gone broody every spring. As a result of her brood, I already have a dozen, 8 week old chicks and am near capacity.
I think all those chicks stimulated something in my other hens. A year old EE from last year's hatch was the next to go broody. A couple days later, my 4 year old "daytime" broody, when broody for real. I kept expecting her to quit after a day, like she always has, but she is totally down with it this time. The two of them have been swapping nest boxes and riding it out together and are now on day 18. Because my normal brooder box is filled with over-flow chicks, I decide to let them sit on golf balls in the nest boxes, and just put a few eggs in the incubator, assuming (hoping) they adopt the day old chicks. I have 5 eggs in the incubator on day 18. Candling looks good. Yesterday, hen #4 went broody. So questions:
1. Have any of you had a broody hen, sitting for a full 3 weeks NOT adopt a 1-day old chick? I could still sneak the eggs under the hens now and let them hatch out under them, but I don't have many eggs and I fear breakage or abandoned eggs due to nest box swapping.
2. If I go the chick adoption route, should I just give the hens the chicks at the same time? Does it matter they are in adjacent nest boxes? I could pry one off a nest and put her in a dog crate, but I'm worried it's going to freak her out now. They are both first time mothers. They are also normally, very easy-going chickens who have not had any issues being around chicks. My rooster also runs a pretty tight ship, which I think helps.
3. For my newly broody hen -- assuming she is still sitting tight and assuming I get at least 3 chicks from my incubator, should I try to see if she would adopt one. She will have been brooding for only 6 days at that point. Otherwise, it's scrounging up more eggs and going thru another cycle.
4. This is a general curiosity question. Do hens get increasingly broody as they get older? My recently broody hen is 3 1/2 years old and has never shown even the slightest sign of broodiness until now. I actually thought she was sick when I saw she spent the night on the nest box, but when I pulled her off, she started up with the tell-tale clucking. Or was it the presence of my first broody proudly parading a big clutch of chicks around the yard that did it? My rooster is pleased as punch, let me tell you.
