I have 9 baby chicks (2 & 3 wk old mix). I've been noticing the last couple of days, especially now that "real" feathers are growing in, that they are "itching"/pecking at their wing feathers, underneath the wing feathers, stretching around & trying to get their backs.... Sometimes it looks like they are cleaning themselves, sometimes it looks like they are itchy. Behind their necks I can see some skin when they stretch, but it looks normal when they are standing there. I don't think they have mites or lice or whatever chicks can get, but maybe I'm wrong? How can I tell? This past week, I've switched from the super fine bedding to the regular shavings. It seems to be "cleaner" than the fine stuff that their waste would just sit on. They love to "dust bath" in their bedding (both types) - it flies everywhere. Any thoughts and/or advice you have would be appreicated. Thanks!
