See I don’t understand that... I have always used DE around my chickens and never had a problem.
DE not welcome here OR effective in humid environments food grade or not does NOT stop the microscopic cuts from occurring all over the chickens skin! Never noticing a problem is not the same as never having a problem if we're talking about breathing..
If we're talking about parasites, maybe you simply don't have them. OR, sometimes what works for one person in one location MAY not work for another somewhere else.
I’ve seen little microscopic bugs on my shirt
The very definition of microscopic is... NOT visible to the naked eye.
Permethrin based "horse fly spray" found in the equine section of most feed stores has been very effective against poultry lice and mites, originally bought to keep mosquitoes off my goats. It's also labeled for use ON chickens with NO withdrawal time for eggs! Use it on the floor, walls, nest, roost, and birds. It has been less effective against fleas (on dogs, requires higher mix concentration come to find out) I'm facing for the first time this year, which my vet has always claimed to be the case.. but I never had an issue before now, having a known vector coming and going between two locations is extremely frustrating.
My location rarely if ever freezes allowing parasites to stay all year. Places that freeze.. get some help for nature. Molting is another natural parasitic control.
Come to find out many including fleas cannot live below 50% humidity.. and so instead of DE.. I would try corn starch, baby powder, etc. Different location have different conditions.
Garlic and acv will do ZERO if you're fighting an infestation.. and feeding a high quality ration not diminished by excessive treats is the number one way to keep birds healthy.. as they were created with their immune system.
I even did only FF for a couple years because all the touted my birds are healthier etc.. nah, not a dime of savings or improvement.. over my standard routine.. and guess what.. my birds are still healthy.
