I am brand new to chickens. I just got in an order of 25 Cornish crosses for a broiler show we are doing in my agriculture class. They're eating and drinking well, however they are starting to lose their fluff on their wings and chests? They also look kinda wet? They are only about a week old, could they already be getting their big feathers in? They all have feathers growing on their wings, but no where else that I can tell. The parts where they are losing fluff is pink, is this because its irritated or is that just skin color? Sorry about all the questions, but I'm really worried about my babies! Like I said, this is my first batch so I have no idea what normal looks like. Thank you so much!!
