My chicks from McMurray were delivered early this morning! All of them were doing great, drinking, eating, and running around. But now there are a couple who don't look right. They are standing with their head straight up and I've seen a bubble coming out of their mouths. I wonder if they drank too quickly or too much and got some water in their lungs. Is that possible? If that is the problem, is there anything I can do to help them? Thanks!
