Okay so I have had our chickens since spring and have noticed one of our hens was slow, lethargic, watery poop... Finally brought her inside our entryway. She’s been drinking water but not eating. Only pooped 3 times in a day and a half, and it’s very watery. I turned on the light tonight to check on her and there are tiny black bugs everywhere on her! (She is a light Brahma so it’s way to see.) there are tons around her vent area and just everywhere on her feathers. I put on gloves when I was checking her out but now these things are everywhere. Of course I was sitting on my couch all night before I noticed these bugs and now I am randomly seeing them on my arms and such. So I look it up and am so afraid my entire house will be infested! What do I do??!
