Does anyone use plastic zip ties on their chickens legs to tell them apart? I have quite a few hens I can't tell which is which!
Checoukan posted a pic of 3 little chicks just a page or two ago that shows zip ties on the leg of one of hers. That does seem like a nice easy method to tell them apart - you just have to leave enough room to cut them off without hurting the chick and replace with a larger one, as they grow.
