I have 3 RIR chicks that are 2 weeks old. One of them is really small. I weighed everybody today, and she's 2 oz. The other two are 4 and 5 oz. I bought them from McMurray, and they're all supposed to be regular RIR. She seems to be eating and drinking normally as far as we can tell. She acts like the others and has no visible problems. She does tend to get pushed around by the others, but I think that's just because she's so small. Can anybody tell me if something might be wrong, or if she's a bantam, or if she's just the runt? She's the one in the middle.
