We recently bought two week old chicks and one of them won't grow like the rest. I know it's a problem with her crop but I don't know which condition she has. One of her crops are inflated and the other is completely empty. The inflated one is squishy but it doesn't smell bad (or I just can't smell it). I've tried massaging her but she wouldn't cough anything up. I've also read that yogurt can help, but the only plain yogurt I have is greek (can I give that to her?) Another problem she has is a possible spraddled leg, but we're already treating that with a bandaid. I'm not keen on getting rid of her because I know she can get better somehow, I just have to find a way.
