Hi new to the site but looking for some help. I have a sick chicken, she is under the care of a vet who has given 2 antibiotic injections, her symptoms are she is lethargic, not really eating, drinking very little and doing poo that looks like slightly beaten egg. I don't know if its related but when i cleaned out my chickens, which i do once a week (yesterday) i found this strange pink thing (pics to follow), it was in amongst the shavings and poop on the floor. I took my hen to the vet today and took this strange thing with me. The vet had know idea what it was and cut it open, the only way to describe it is it has chambers inside i couldn't get that close but my sister in law, who did dissection at school said it was similar in look to the inside if a heart. so if anyone has any ideas what this thing is and if its related to my poorly hen please let me know. the shavings stuck to it are from the coop floor and i think the black is poop. i know it is not food that anyone has given them and they have taken into the house because they don't do that, and i haven't got a rooster if that is any help.
