Eggs

[ducks and geese]

They have grass through out the day and I'm wondering if the oyster shell will harm the males because I have them in the same pen

I wouldn't worry about it hurting the males.
My males get the same diet as the females (they always have) and I've never had male with any sort of health issue (though they can get fat quick!)
