I posted this earlier but I don't think I put it in the right section. I found one of my 4 day old chicks dead this morning. I got them through the mail on Tue from My Pet Chicken. It was a buff polish chick. I have no idea what she died from. when I went to bed last night they all looked fine. I guess it could have been stress from traveling catching up to her. Also I have heard a chick sneezing. not very often and I can't figure out which one is doing it. they all look the same health wise. Is this something i should worry about?
