Here's my situation. I have three and only three chickens, all hens, that went broody and hatched out clutches of eggs the first week of May. The first clutch is about a week older than the second two. Because the hens were so agressive towards each other after the chicks hatched, I 've been keeping each hen and her chicks in separate pens. It's been something of a headache playing musical chicken pens, especially on rainy days, since my tractors aren't roofed. The hen with the oldest chicks (now about 5 1/2 weeks old) is starting to get very grumpy toward her chicks, one in particular (a little roo). I started to hear shrieking coming from their pen yesterday and noticed that instead of calling her chicks over to food she's found, she pecks them when they get under foot. It seems to me she's ready for them to grow up and move on....except that she's still defensive on their behalf if she senses a threat. One of the chicks got left behind in the run and as I was trying to shoo it out from under the coop with a rake handle, this hen came running from the other end of the yard to attack the rake. I would separate this hen from her chicks right now, except for two problems. The hen would have to be alone, because I have no other chickens she can join right now. She certainly can't join either one of my other two hens with their chicks. These hens are still content being mothers. And my other problem is lack of housing. I don't really have a fourth pen to keep this hen in all by herself. When the other two hens are ready to leave their chicks, I can put the three adults together, and split the chicks into two batches (bigger and smaller). That should work. But in the meantime, I'm kind of stumped. Any ideas?
