Hello, I have a 12 day old chick that is struggling. She is not as big as the other chicks and her crop was very hard yesterday so I gave her a bit of olive oil in some moistened food and started very gentle massaging. It was softer and smaller today and I'm still massaging a bit. But I'm wondering if it's something else. She digs at the side of her face and beak a lot and I can see her low cheeks and under her beak puffing out with each breath. None of the other chicks are doing this. She sleeps a lot and I wonder if she's having trouble getting air and oxygen. Thoughts?
