I read to put backing soda in the water, its been used to flush the crop. I bought a syringe and a tube to go on the end from the Vet office. You will need another person to help you with the flush. I stopped giving yogurt and boiled eggs. She looks at it and shakes her head at it. The yolk of the boiled egg is nice we're it disolves. I started giving my hen her crumble softened up and she is loving it. She had a normal small poop about an hour ago. I think that's a good sign, I'm concerned about the goop. I think it's blocking her from absorbing her food. I have only smell sour crop yesterday, however, the previous days no smell. It's been day 8 I think. Losing track. I see you have been at this for almost three months. You must be exhausted. I dewormed her as well. She did have worms. Tinny ones just in case that was part of her problem. Shes fluffed up for two days. That worries me.
