I know this topic has been beat to death because I've read nearly every one. What I can not figure out is the proper dosage. Everyone seems to have their own formula and methods for this and what I would like to know is which one is the right one? I hoped I could get away with using the injectable ivomec as a spot treatment and I tried this 2 days ago. I just checked my young sultan roo and he's still got active mites. This is a heavy infestation Since all my chickens are feather footed they seem to not dust bathe really well. I sprinkled 7dust over the coop and main areas of the yard they visit, also dusted the aviaries and dusted all the chickens last week, 7dust did not seem to touch it. Can I mix the ivomec into propolyen glycol to make a spot treatment? (I have some for perfumery so it's safe for humans on skin) Again, I read use internally by giving the chickens bread with ivomec on it but I am not too sure they would eat it. Any ideas on this? My chickens are 5 adult sultans, 2- 5 month old sultans, 2-4month old mille fleur bantams. Unfortunately next to the chicken coop is a coop of bob white quail that are 2 months old. There is also a English budgie aviary, cockatiel aviary, button quail, coturnix quail and pheasants. All would have been exposed since the chickens are free ranging during the day and love to clean the seed around the aviaries. For the majority of the birds I would prefer to use in their water bowls. But some have chicks and I don't know that this is safe. So questions to answer are: 1. Amount of ivomec injectable in water for the various birds I have 2. Can it be used in spot treatment on the skin or is there a formula or recipe to make it? 3. How long after usage or application before mites die? 4. When to use again after first usage. 5. Is it safe to use when I have chicks in nest boxes (budgies and cockatiels) *The other birds do not seem to have mites, only the chickens so ivermectin would be used as a preventative in them. Thank you!
