This morning I saw some blood on my one year old hen. I put on some gloves and went to look in to it further. At one point I thought it might be a prolapse as I saw a big bubble thing come out so I pushed it back in. Later on I noticed flies round about her so I put her in a separate run from the rest where she still is now. She has no grass with her but there are still flies around her even after I gave her a warm bath. Does anyone have any ideas for what I should do?
