3 Females. The one on the far left looks like it has a bald spot from feather picking or bugs.
I've used a spray called Poultry Protector. It works amazing. I've used citric acid like lemon, orange, and lime juice. With the citric acid you have to put a high concentrated area near the tail and inside the wing so their face touches the droplets of citric acid to kill some on their face. Sulfur works great to for all kinds of parasites. Garlic powder contains 17 different kinds of sulfur. I give them a bowl and keep it filled until they stop eating it and I'll sprinkle some Garlic powder on my birds back and in their wings. So far haven't had a problem with bugs since I've switched to all these things I use for parasites. Though Safeguard I would definitely use for peafowl that are a year or under since that's when they are most vulnerable to parasites. Sure they can handle some but once they are older than a year they have a good immune system but sometimes may need a little break every now and then. I'm sure ricebabyca can give you more help on the medication. These are just some of the things I use and other people in Idaho have helped confirm my method.What other product for bugs/mites?
