Hello... We just moved in May to 5 acres of property outside of Jacksonville, Fl and just had to add chickens. Currently we have 3 Cornish Rocks (1rooster & 2 hens). 9 chickens in 1 flock that have 2 roosters and 8 in another younger flock with 1 rooster so far. I want to join them together because of shelter and laying boxes. That way they all have the same access. Is this possible???
