I know that this has been beat to death and I did do a search but it wasn't definite enough for me. I have a RIR, 8 months old, egg production has been down to 3 eggs a day out of 6 girls but I attributed it to lack of light in the coop since its winter time here. I noticed yesterday that she was missing some bum feathers and the area was a bit red. Today, it has a lump now. I picked her up, she was mad and felt around. It feels like an egg up near her leg? Good grief, what do I do?
