I have three Buff Orpingtons hens and they are just starting to lay. The trouble is I can't tell one apart from another and I wanted to know who was on the nest. So today I think I solved my dilema. I went to the Dollar store and bought a packet of hair scrunchies with pretty silky ribbons sticking out all over. I slipped a different colored scrunchy oven the wing, at the shoulder area of each hen. So now I know who is Rose, who is Blueberry, and who is Violet.
