Hello! Last Friday we received a shipment of 21 chicks, all happy and healthy from Ideal Poultry! YAY! They are really doing well. Tomorrow they will be a week old! However, this evening I noticed one of the Brahmas has begun to limp. I have checked her legs and they seem fine, no noticeable issues. She will walk around, then sit down, and seems to limp when she gets frisky. What do you think and what should I do? Thank you, in advance, for any and all advice!
