I have 10 chickens currently laying and my boss hen is a Rhode Island Red with a
spicy personality. All but three lay some shade of brown egg, the others lay blue/green.
I currently have six nesting boxes so there never seems to be an issue with fighting over laying space but the boss will go through the boxes, kick out all the blue eggs and leave the brown/tan/cream. Is this a thing or something coincidental?
