We got our first ever 'flock' in May '11, never had any problems, excellent layers, they do free range, etc... we added four more to our flock in October, everyone seemed okay, all was well. Our first set of chickens started laying in the fall and by November went broody. Two broodies hatched out four chicks combined. One died the next day from what I thought was cold and left it at that. I brought the remaining three into the brooder inside. Everyone was eating/drinking/sleeping/pooping and happy this morning, but about an hour ago they started making a raucus and I looked in and one of the chicks neck kept turns back and to the side and it's back leg was stretched out. It's flailing around and peeping, slight tremors, generally looking like we need to explore taking action soon. But could this be this Newcastle I've read about? What do we do? I don't *think* we have a county extension office in Canada, not sure what the equivalent might be... do we need to take out our entire flock now? We're moving to a farm in February and while I don't think the other two neighbouring farms raise chickens I don't want to bring diseased animals near anyone elses', nor do I want to have to cull the entire flock. What is the right thing to do? They haven't had any vaccines that I'm aware of as they came from breeders online, some were 3wks old and some were 10wks and I just don't know what to do! ETA: These chicks are only 48 hours old and eating non medicated chick starter Thank you!!
