I have a cochin pullet who is not doing too well. She is having a flare up of her CRD because of the cold and her severe lice infestation. I dusted her with Sevin powder today as well as started her on Tylan. Can I mix her antibiotic and dewormer together in her water? They all need to be wormed and I'm afraid she has worms that are causing her pale comb/wattles.
