Hey everyone, new to chickies and had a quick question..So we have 16 chicks total now and just got these 4 today. 2 are meat birds Cornish X, and 2 are Ameraucanas. I had gotten 2 of the Ameraurcanas a couple days prior from the same batch and didn't notice any of the birds with this on it- bump on chest. So the 2 Cornish X chicks all are at a couple days old and one of the Ameraucana chicks have this tumor or round 1/2 dollar/quarter size round tumorish bump on its chest. I thought it could be normal for the meat birds since they get broad chests was my figuring but then the 1 Ameraucana had it too. What is this and is this normal? Does anyone know or should I post it somewhere else? Should I return these guys? None of my other chicks have that. Please let me know. Thanks!
