How do I up the protein in their diet? I have read that cat food helps. I have also read that cat food is bad for chickens.
Lice and mites need to be treated twice at a 10 day interval, to kill the emerging lice/mite eggs....You can dust them with "Poultry Dust" which is a pyrethrin, with little of no withdrawal time. That's the only approved insecticide. Sevin dust is also very effective on the birds and in the coop. Ivermectin kills internal and external parasites, except tapeworms. I will use all these products at different times, depending on the problem at hand. Sometimes not eating a week's worth of eggs is worth it in the long run... Mary
