I have 3 Marans Hens, who laid nice Chocolate colored eggs--well not the darkest, but certainly dark enough there was no question they were Maran eggs. Now, they are barely tan--wonder why? I know these are from my Marans, as I only have Americanas, and 3 Black Sumatras, besides my Marans. and I get 2 of these eggs pretty well every day, and the 3rd one is broody. I feed regular egg pellets from the local feed store, and toss out the occasional couple cups of BOSS, and then the occasional cantelope rind, cut into pieces so everyone can grab a share. Occasional tomato, cucumber, etc, peelings. Any ideas?
