We got a mixture of 4 Rhode Island Reds and Buckeyes. They all seem to be doing well and are a week old. 1 chick is bright yellow and much less feathered than the others. 1 has a crazy mohawk streak from his head to tail feathers and is much smaller. The chick that is by far the largest though doesn't like to stand up. Her feet are bigger but so is she. Every chance she gets she lays down. Even when she's walking its more of a waddle. I'll try and get some video of her and post it up on Youtube so everyone can she what I'm talking about. Is this something I should be worried about?
