People moved, left two chickens on their own about a month or more. One isn't doing so well. Hardly moving, white pasty poo on her butt. Researched your great site and she might have vent gleet? I've added ACV to water, have small dish of 0% fat Greek yogurt out with her, going to attempt to wash her with Epsom salts in a bit, added a 'stress' vitamin mixture to another dish of water...BUT I'm just not sure if this is what I am dealing with as I am so new to this...any feedback that helps me with this would be so kind and appreciated.
