My BR has been hanging off by her self for a couple days. She finally let me close enough to her and she has a prolapsed vent. Can I push it back in? Does anyone know the success rate? Is it more humane to cull? I believe she is 3. She was always a wrinkly egg layer or a soft egg layer. My other BR from the same clutch was an internal layer and sadly had to be put down last year. Is this stuff hereditery?
