So in my newness to owning chickens, last fall I bought some layers from a swap meet. I promise you, I don't need a lecture because boy have I learned my lesson. First my whole flock got infectious bronchitis. So I battled that for a few months. But over time I have noticed my girls getting thinner and there combs getting lighter. I honestly thought it was because winter got cold here this year. Only to learn after treating my rooster for a very bad case of bumblefoot that I have a lice infestation. So I have treated them with ivomec pour on and will do it again at 10 days post the initial treatment. I spent 9 hours cleaning, disinfecting, and spraying their coop with pymetherin. I will repeat this process once a week for a month. So what do I need to do next to get them back to a healthy weight and build their blood back up? Should I worm them, also, since ivomec only treats for roundworms? I haven't seen any evidence of worms but I just want my girls happy and healthy again. Any help would be appreciated. I have heard good things about red cell but I don't know anything about it.Thanks fellow chicken lovers!
