Ok so I bought some chicks and this is my first time shipping. I got BLRW and bramhas. I have since lost two blr and now one is in the brooder limp as can be and gasping for air. I dont think it has long. I hold it in my hand and its neck is limp and just lays there. What am I doing wrong??? I check them for pasty butt, they have plenty of food and water. They have heat lamp and an area where they could get away if to hot. Everyone else is eating and drinking its just a sudden thing. I dont know what else could be causing this??? Anyone got any idea's?
