I have two black australorp hens, a RIR hen, and an ameraucana bantam rooster who get along great and are all about 8mo-1yr. They've been together for about 5 mo. now. Yesterday, I bought a cuckoomaran and an easter egger, both about 1 yr, and I'm not sure how to introduce them. I put them in last night when everyone was up for the night, and this morning some major bullying was happening. The Easter Egger is being bullied bigtime by the Banty and the RIR, but when they dare come near to peck the Cuckoomaran, she fights back hard! Will they ever get along or do I need to return these chickens to where they came from??? I'm not familiar with the temperament of Cuckoomarans...help? Second question: what do I keep my eye out for to make sure these newbies don't have bugs or diseases!?
