i have a chicken that i am sure she is laying these light brown but very brittle shell and blood in the yokes. not much blood, more of a blood spot. i know she is young, but not sure how young since she was given to us. she looks like an easter egger. she is shy and runs away. she was very tiny when we got her and she has now put on some weight. her best friend is my rooster. they are together all the time. they eat together and sleep at the same time. they are all eating the same (19 chickens ) she is the only one her breed here. and is one of our fav. her name is dolly.
