Ok checked on my mini flock today and as I was getting ready to open their nesting box I noticed where one hen had laid eggs in a differant area and ran in and pecked at an egg, ran off with the shell. I cleaned the area and removed the eggs to an incunator for safe keeping. Added more nesting material and put ping pong balls down. As to any stress factor neighbrs dogs have started bugging my yard and we have a feral cat issue. Working on a solution for this part ^ Hen ran with the shell but left the yolk behind. Could this be a sign of needing more grit?
