Hi everyone. I am new to the chicken world. So much to learn. I am worried about one of my chickens. She is smaller then the others, more skittish and her feathers are seem to be developing later then the rest. Plus they look curly or scraggly at the tips. I tried googling and all that comes up is the frizzle breed, but only some of her feathers are curly and she does not look like a drizzle to me. Could she be sick? Thank you for your help in advance. I have attached a pic I took of her this morning.
