My chickens are getting these fleas on them. I first discovered them last year on my cats and dogs. Did research and found out what they were. I was able to remove from animals. I dusted the chickens, coop and boxes with DE. They seemed to go away during the winter months. I keep checking the chickens and don't see any. There is a rabbit that lives in the pen with the chickens and i noticed last week he had some on his nose. This is the first time for him, saw them on the cat last nite. So most likely will be on the chickens too. I have 35 chickens so trying to do the vaseline on each one is hard. I can do the DE again but would like to treat the yard. I read some where that I could put adams puppy flea spray on chickens and the yard. I also have Sevin powder to use. My biggest concern with using sevin and spraying the yard area is the bunny. I dont know if any of this will harm him. He comes out in the morning and evening ans lays on the cool dirt. Does anybody have any suggestions. I need to get it under control before its out of control. Thanks
