I have 12 Runner ducks (8 female 4 male). The ladies are laying like crazy now. I'm getting 7 or 8 eggs each day. They are on Blue Seal Grower. I have free choice oyster shell and grit available. They are inhaling the oyster shell. They are eating several pounds each week. Their egg shells are like rocks. Is this typical? They are living with two geese so I am trying to satisfy feed requirements for both.
Thanks
