I agree - space is probably not your issue. This is where it gets tough. You will have to decide whether or not you want to keep one that's already that aggressive toward your other birds or not. I honestly don't know what I'd do in your shoes...Thanks for the suggestions
My chicks are in a small chicken coop at night. It's only at night for sleeping. it probably 2' by 3'. They huddle together in about a square foot area, maybe a tiny bit bigger, while sleeping. there are 24 of them. They are 5 weeks old bantam chicks. Still very tiny compared to a standard size chick. In the morning they are released to my large unfenced yard. As are my other grown chickens and ducks. (My grown chickens, and my ducks have separate coops)
I have a separate area to feed the chicks that the other birds can't fit in. The chicks can come and go as they please. They don't stray as far as the older chickens but they have lots of shrubs, trees, dust areas, grassy areas, and a small compost area near by that they love. The older chickens eat breakfast than go out away from the "chicken village" we made. Oh and they have 2 different water stations about 6+ feet apart.
I don't think space is the issue at all.
"chicken village is an area where the coops are about 5 and 7 feet apart in a triangle with 3 feed stations. the chicks feed station is attached to their coop and the other stations are 6+ feet apart next to the water.
The big chickens rarely even peck at the chicks. They certainly never drew blood.![]()
