I took in a rescue rooster (of sorts). Seems to be about a year old BCM. He came with a heavy lice infestation, feather loss, and pecking injuries. I've had him for three weeks (separated from the flock of course) and have dusted him weekly with garden and poultry dust. His skin is healed, he has feathers growing back, and there are no signs of adult bugs. He still has a number of feathers around his neck with eggs attached. What do I do about the eggs? I figured everyone would be hatched and killed off after three treatments. Advice please?
