What color is she? If she’s a lighter color I recommend slowly checking her body and feathers for lice and/or mites, it may be hard to see but with close vision you might be able to see small little dust looking bugs crawling through the feathers of your hen. Do you have Diatomaceous Earth on hand? I recommend just in case ruffling some of that in your hens feathers and just sprinkling it around the run and coop of the rest of your flock as lice and mites can spread. This is not 100%, but it’s better to be safe then sorry. Also try putting garlic powder in their food or putting a clove of garlic in their water. if you can’t Do that maybe give them apple cider vinegar in their waterHey everyone, I have a sick hen. She is about 1 1/2 years old and going through her first molt. The last week or so she has been lethargic and unenthusiastic. Her comb has been flopped over, she puked a bunch of water and has had bad diarrhea. She sits all puffed up and doesn’t move much. She is a champions layer and we would be devastated to lose her. What do I do? I’m very worried about her.
