My 3-year-old Barred Rock hen Layette is not a happy camper. The first symtom I noticed was her gasping a bit while breathing. I just culled another hen last week who was really wheezy & hoarse, so I thought Layette might also have some respiratory ailment. She wasn't wheezing, but breathing hard & slow, and holding her head up and breathing in & out of her mouth. I separated her & have been giving her Vet Rx and antibiotics/electrolytes/vitamins in her water. Her gasping has stopped and her face looks good, nice bright red comb & wattles, clear eyes, no more gasping. But her abdomen is really swollen, heavy & solid-feeling. She's been making small poops and there's some sticking to the feathers below her vent. She hasn't laid anything in her cage, but I wasn't expecting it from this older ill hen. I'm going to start treatment as if she's eggbound, something I haven't yet done on any of my hens. I'm going to give her a good long soak in warm water, take a feel inside her vent, put some veg oil in & around it. I'll give her soft foods to eat. I'll darken her cage. What other symptoms should I be looking for? What else should I do to treat her? Thank you for your input!
