Hay guys I have had a hen that look to have a sting bumb right at the mouth and started to ferment and turn into a hole does anyone know what this is. This is the second that this has happen to! I going to have to put her down because food falls out of the hole and now she is starving! And her beak is jigged to. I will post pics and I picked her up and it reeks (her head) I think she is rotting from the inside
