My mom and i discovered the chickens have a bad infestation of mites one hen i saw them all on the crevice above her eye she must have 50 or more mites on her i feel bad for them and my mom didnt see them until there heads were bald and me and found out that our Tractor Supply has Diatomaceous Earth Food Grade so set a bag aside for tomorrow when my mom comes back and then others are saying to get Sevin Dust my mom said she might do both and also what should we give to the hens to build up their iron to stop them from being anemic??
