I got a lot of info from Backyard chooks when researching my initial problems but I am still having issues hoping someone can help more. My ISa brown first started laying oblong egg, then they I started to find them broken, was worried she was eating them when I noticed her in the hose for along time but no egg. Checked her out and found mites and re inflamed skin all around her vent. Could feel no egg. Treated all 3 hens w Ivermectin and neem powder, thoroughly cleaning the hutch and powdering everything including their dust holes. Checked next day and found small prolapse that looked pretty fresh. Popped back in easily, kept her in the dark for three days using anusol around the area to decrease inflammation. This am was to be her last day in dark if all was well (start of day 4). There was a very rubbery, broken egg! She did not prolapse but the skin around her vent area is still very inflamed. No sign of mites. She was on a laying feed, but in dark I just gave her mash. She is free range. Other laying hen is fine, pullet hen seems fine. Worried I am still in for trouble, any more advice? Don't want to loose my chook!
