Does anyone know what this is? It came out of a chicken who has not laid an egg since March 5th and she is 4 years old. She is acting a bit slower and possibly in the beginning of vent gleet, which I am treating her for. It looks like a translucent membrane to me, it stretched when I picked it up, does not have anything in it but clear liguid and does not seem to be a worm. No movement, nor is there a head and so on.
