I have 4 hens, about 7 weeks old, that are running out of room in the brooder...fast. I have two pens, 1 that can hold 11-12 birds comfortably and a tractor that can hold 4-5 comfortably. The big house currently has 3 hens, 1 rooster and 5 2 week old chicks. The tractor has 2 hens and 1 rooster. I thinking about moving the 2 hens from the tractor to the big house and, putting the young birds with the rooster. I feel like this will work because, the rooster in the tractor has managed a flock with chicks before and was very good with them, calling them when he finds food and such. The 2 hens that would be moved are larger than the 3 hens currently in the big house but, the momma hen of the 5 2 week Olds is the most dominant of all. I think if I move them at night, it would go over with minimal stress to all the birds. Any feedback is much appreciated.
