I just received 15 chicks from Ideal yesterday and it's my first time ever to order chicks. I have a couple of questions. All the chicks seem itchy because they are always scratching at themselves and preening (or that's what it looks like even though they don't have feathers). What's going on? Do they have mites? If so, how can I treat them? Another thing I noticed is one of the black sex link pullets has crooked feet. Her toes curl in almost like she's trying to hold something. Can this be fixed and will it effect her quality of life?
