Not sure where to post this question. I have four chicks that hatched Tuesday through early Wednesday morning. One of them, instead of drying and fluffing out like usual, she has an area on her back and head where the stickiness dried hard, almost like a shellac coating. I tried washing it off with warm water and putting it back in the incubator but it's still about the same. Anyone ever seen this before? Do I need to do anything about it, or as the chick fluff grows into feathers grow out will it eventually just go away? She seems fine otherwise. Running around with the other chicks and eating and drinking normally. Here are some pictures:
