Ok, I have some easter egger bantams (2) and buff orpingtons (3) hens. I'd like to get a white silkie, 2 black cochins and at least one crested polish (all hens). Will they get along? How should I integrate them? We only have one coop - an 8'x8'. Will they get along or no? Also - is $7 for silkies and cochins and $5 for polish high or good? Thank you!!
