My frizzle chick seems to be having issues. It was given to me along with another the same age, about 3 weeks. They looked pretty sickly when I got them on Monday and the one is looking better now but the frizzle is still not looking any better. Her feathers are thin and nonexistent in places like on her underside and under her wings. She has a large lump on her neck and I've been informed it's just a full crop, hers doesn't fluctuate as much as my other chicks though. I'm having trouble uploading images but the lump has sparse feathers and it's kind of a yellowish color against her pink skin and you can see little veins on top, could it be impacted crop?
