We recently bought 6 new pullets for our coop. We bought them at a local supply store and when my husband went in today, the woman mentioned that the chicks had Marek's Disease. She couldn't give us much information, but the store still had all of their chicks and she didn't want to tell anyone in management for fear she would get in trouble! This seems crazy to me that she would risk all these chickens and coops they may go to by not telling.....but she has been wrong about chickens many times before. My question - is it safe to eventually combine these birds with our coop? We have 12 chickens currently between 1-2 years of age. Right now, the pullets live in a brooder in the garage so they are separate. We bought 3 pullets the first week of February, and 3 more about a week later. If she said one of the flocks was affected (but wasn't sure which ones) wouldn't we be seeing signs in our brooder since they were in two different shipments to the store? I hate to cull any of our chicks, but I would rather not have to cull my entire flock that I'm rather attached to. Any help is greatly appreciated!
