We have 17 Dominique chicks in a brooder right now at almost 2 weeks old. My wife has decided she would like a couple buff orpingtons!!! Is it OK to go ahead and put them in the same brooder with all my other chicks at this stage or would they be unfriendly towards the the new tenants???? We have a big enough brooder I think its about 3x5 ft!!! Any help would be appreciated!!!!
