my little barred rock petunia went broody. i could tell by the way she was actiong ruffing her feathers out in the yard she was just acting different i thought ok maybe broody. so last night she was on the nest still on it this morning. i think there maybe 2 eggs under her and of course they cant hatch poor baby. i only have two hens big enough to lay eggs. we have 3 nest boxes but they will only use one. what will poor rosey do when she wants to go lay her egg and petunia is still sitting? what do i need to do about this please?
