Well last night I joined my entire flock together, 9 big girls of 9 months of age and 4 pullets of 3 months of age and for the first time ever 1 rooster of 3 months old. I've got a camera in there and keep checking on them this morning. so far so good, minimum pecking. Last night when I first put them in, one of the pullets cried pitifully and broke my heart but it had to be done eventually. That darn rooster with the other 4 little girls was getting way to heavy to carry to the brooder/grow out box in the garage every night and morning.
