My Red Star, Rosie, has something going on. I love my chickens, I have four, but I know I'm far from knowledgeable about a lot of things to do with them. For the past week I could tell she didn't feel great, her tail feathers were pointing down, hunched over in the butt area, her butt a little dirty. Then Thursday, she passed a rubber egg shell, I saw her standing and pulsing the vent, it wasn't right, so checked and saw a deflated rubber shell was coming out, so I helped that come out, and I hoped maybe that would be the start of recovery. But she's still not right, she'll stay in the run when the other three come out for a walk. I've upped the calcium, not a drench, but sprinkled on the food. I have been mixing some probiotics into the water. Tomorrow I will try a nice bath with epsom salts. I look forward to hearing any advice. Thank you.
