I have 6 week old chicks (10 of them) in a separate run, and in our main coop we have the rooster, broody momma, and 10 chicks that are about 4 days old. When would I attempt to combine this flock? The older chicks are with a few turkeys and I'd like to separate them to give the turkeys more room but don't have another run/coop for them yet. Is it best to wait until the chicks are all comparable in size? P.S. this is the first time we've had chicks raised by a hen and it is just amazing. It is so much more fascinating than raising them in a brooder. I love watching the mother hen and her little chicks! Just love it!!!!!
