I'd like to know if this is typical behavior......when the chicks get ready to sleep, they all cuddle together and bite at themselves...like they are itching. One chick that is pure white, I can see definate redness around the neck and base of tale feathers. I do not see mites, but the chicks seem to be itching. Is this typical? Is it typical to see the very pink skin so well on a white chick? I've posted about this but can't seem to get an answer, so I'm trying this route.... Thanks!
