I know people have asked about this before, but I can't find any advice that is specific enough for me to feel comfortable administering ivermectin to my birds. (A lot of it seems to vary) I have never had to use ivermectin, but I have several birds with scaley leg mite that have not been improving much with topical treatments. I want to use ivermectin, but keep seen different dosages and methods of administration I would like to administer orally. Please advise me if you have done this a lot with good results or been advised by a vet as to the dose. 1. Which ivermectin? For cattle, concentration, etc. Which should I look for - I have noticed that my feed store carries several different kinds. 2. How much for different size: Bantam Cochin, d'Uccle Light laying hens - Leghorn, polish, EE Laying hens medium - Rocks, RIR, Large hens - Giant Cochin, Orpington 3. When should I repeat treatment?
