I have an Orpington that I'm not to sure on her age, I got her at 5 weeks and haven't really been keeping track. She disappeared for a day and I found her stuck behind some firewood. I think she was dehydrated and hungry because she couldn't walk, just sort of rolled head first. I brought her in the house and gave her water and food. She rested overnight and only drank some water. This morning she was up and moving around very slowly but not totally tumbling around like yesterday. Her balance is awful and she falls back or forward but tried to correct with her wings, she's been eating like it's going out of style today. I figured she just needs to build up her strength but when I was looking her over I noticed her "butt" doesn't have big feathers just the downy ones so I took this picture. Because she's a teenager I was thinking that her adult feathers are just coming in? She's also been scratching at it but then I saw a bug that I would say looks most like a flea. From things I've read I think it's too big to be either lice or mites, it's very easy to see. So my question is could all of this be related or just a case of this chicken having a bunch of problems? Do you think a DE bath would handle whatever the bug is or do I need to actually wet bathe her, because I would rather not with her feeling crappy and all. The rest of my flock are adult layers and they don't interact with this one who I have in her own "teenager coop", but none of them are showing any similar signs. I also have 5 dogs none of which have fleas. Thank you!
