Im glad big fatty is doung well. Also if you don't already, I would suggest giving them a place to dust bathe. It helps to keep external parasites like leg mites and feather mites away Just in case. I had a hen who laid the leathery shell without the yolk and I was sad to see her pass half a year later. And has anyone know how to deal with vent discharge and what causes it? I have a few older hens who have a little.
