Hi I am new at the chicken thing, I would like to know if I can worm my chickens during moulting? I see no evidence of worms but I just bought 5 new rhode island reds and added them to the coop with 4 cochins who are in the middle of a moult, I dont know much about how these girls were cared for. They appear to be healhy, I did dust them with DE before letting them in. I dont know if it is necessary to worm chickens every now and then or not?
