CornishX Chicks...help!

[OzarkChooks]

Thank you for the extra pic. Their living situation looks pretty good. Cornish cross do "bald" in surprising spots sometimes, but this usually happens after they have started to loose their fluff or after they are fully feathered. If it's not poop or some type of dirt on the skin, it could be a mild skin scald potentially from something like: it could have splashed in the waterer and then went to sleep for the night with its neck on a fresh poop, for example. Probably not anything to worry about unless you see more chicks with the same thing. If you do see more of it, you'll want to refresh their bedding and/or somehow mitigate their getting wet in the water. If there is not much air flow in the brooder, things can take a while to dry out and that can sometimes be a factor.

They do make a mess with the water. I wonder if they will use a nipple waterer instead. Thank you!
