Four of my five are growing great except for the tiny one. I hope you tell in the pics. She is half the size of the others, is eating okay, drinking and pooing alright, but just doesn't seem to be growing. She is developing new wing feathers to some extent but not as far along as the others and now she is limping for no discernible reason. What may be the cause of her delayed growth? And what do I do? And why would she be limping? She sleeps a lot more then the others, but also can be pushy when needed. Also she is very heat seeking. So I know that's a lot of questions but an insight would be greatly appreciated. They are two weeks old on Monday.
