I have a very badly injured roo in quarantine right now because our gander beat the crap out of him. I am sure it’s because he was eating a chicken. He’s an asshole rooster but I still feel badly for him. Has hardly any feathers left and bruised from head to toe.
I bake and crush my chicken and goose egg shells and put them in a bowl in the coop. The geese love them when they are laying. My gander doesn’t touch them, just the females.
