Well, I just bought some new B complex today that wasn't time releasing and I gave her half of a pill earlier today. The stuff that I just bought that I will now continue using has 5mg of riboflavin in one pill, so that would mean I'm giving her roughly 2.5mg of riboflavin a day. The other vitamins it has in it are Thiamin(B-1), Niacin, B-6, B-12, Folate, Biotin, Pantothenic acid, and vitamin C. Also, is Mareks contagious? Because I used to switch her and the bully who targets her into the coop with the rest of the chickens and none of them have shown symptoms. Also, do you have a diagnosis for the bloody nose?
