Vet diagnosed mild prolapse yesterday & gave metacam & amoxicillin. Fecal negative. For 3 days she has froth on sides of her beak, today subsided then an hour ago blood & some bloody froth. She ate crumbles, grit & water today, no regurgitation seen. Poop normal, then few hours ago one smelled like rotten meat, then others ok after. Crop was softer. Rattles beak like saliva/froth coming up? Noticed her eating some pine shavings a while ago so we took her out of that area. She's trying to sleep now & a bit of raspiness to her breathing, takes a few shallower breaths then a bigger one. Respiratory/heart/crop??? Foreign body/infectious disease?
