I purchased what was supposed to be cornish cross chicks about two months ago. Below is what they look like now. I'm new to chickens but I'm pretty sure these are not cornish cross. They were yellow with a little white on them when I bought them at about 1 week old. I asked the farm supply where I bought them and they said that if they were cornish cross they should be white and quite large by now. They said that it is possible that they got mixed up when they got mine out. Here are the pics. Any idea what breed they are?
