So after being gone for about 7 hours I come home to find a female in a pen with eleven other females and six males (approx numbers) and one of the girls is going smooth off. This has apparently been going of for a while because the males were pretty upset. She was chasing other birds and pecking. I did not see where any blood had been drawn but I went ahead and moved her to another pen with fewer birds, the same thing happened within just a few moments. From there I put her in a place by herself until I learn better. Any ideas? By the way, the birds are 4-5 weeks old and have been in these pens for a while with no trouble. There food and water was still good. Thanks for any help.
