I purchased chickens from a hatchery, I ordered an assortment and I believe one of them is a cornish roaster. It is much bigger than the other chickens. I have no experience with this breed. It is not walking around and doesn't move when the others step on her (I'm just gonna assume it's a girl). I decided to pick her up and try to make her stand but she didn't she can "crawl" but doesn't get up and walk. I have moved her to her own place and put food and water close to her so she can get it. Like I said I don't know anything about this breed, I don't know if this is normal that they are just lazy (which I doubt) or if she somehow hurt her foot (don't know how she would), or if she is sick. I have been giving her the same feed and care as the other chicks so if there is something I should be doing different for her please let me know. She is only a month old, I would hate to lose her.
Thanks!!!
