I have a week old chicks I ordered from McMurry's. The chick is a silver lace cochin. He has a growth on the side of his chest & his neck is wobbly. He is very sleepy, too. I am making sure it drinks & put chick food in front on him( he is laying most of the time) he is eating. He is still walking a little. What can/could it be????? He doesn't act like it is in pain. Thank you for your help!
