I got a bunch of chicks including two cornish, but one of them didn't make it. Anyway, the other one is about 4 or 5 weeks old now and has a rather large breast area (which is obviously why it is a meat bird!). Anyway, I put the chicks outside today, and all of the chicks can climb up the ramp. Except the cornish. Is that normal? I had the food and water at the top, but I moved them since the cornish can't get up there to eat/drink. It was eating some grass but it didn't look comfortable like the other chicks.
