Scenario: I have 3 chickens and a duck - they live in 2 chicken tractors. Horrible arrangement for the winter months. So by the end of this month I hope to have a new 10x8 coop. Now - my niece is 'raising' 5 new birds to add to my 3. She gets them while they are chicks - handles them, get's them use to people and then when they are too big for the city they come to me. SO the ? is this --- do you think I will have just marvelous success at the older birds (they are only 1 yr old) accepting the new birds if I put them together for the first time in the new coop?? Will the new coop cause just enough 'neutral territory' and confusion to cause the 3 yearlings to accept the 5 newbies along with the new coop situation?? Just hoping someone will say "OH YEAH, that it'll work for ya!"
