9 month old Nankin, has been laying eggs fine until today. Very swollen red vent, panting heavily, eyes closed, drooping tail, bright red comb and wattles, not moving much. I sat her in a warm bath, also tried masagging her abdomen. Put a bit of oil in and around her vent. It's been over an hour. She has not passed the egg yet and is in distress. Any other suggestions? Thanks.
