I noticed one of our hens has been sitting in the nest box constantly and her comb and wattles have gone pale. I had DH check her for mites and he said he saw a bunch near her vent. He said it looks like she is still laying though and he has seen her eat and drinking okay. She does look sick though. I've read a ton of threads about mites but I'm not sure if Sevin or Eprinex would be better? If she is already ill from the mites I don't want something that will hurt her, but obviously the mites need to be taken care of right away. Can the eggs be eaten if we use either of these? I can dust the coop and boxes with Sevin too, right?
