Hey guys! So I have this really weird thing going on with 6 week-ish old my brahma chick. He isn't growing up and he's bald!! All my other ones are thriving and fully feathered. I am 100% positive he is getting food and water. What's going on here? I feed Alaska Mill and Feed chick crumble and grit. I've always fed this to my chicks and have never had a problem. Any help would be much appreciated
