Hi. I am going to look at a prefab coop 8 chicken and 2 roosters. Sounds like he got them young. Only had for about 5 or 6 months already laying eggs. He did not investigate rule very well and is not allowed to have them and needs to get rid of them. I am still very new to this. Any pointers on what I should look for when looking at these chickens?? Thank you in advance.
