We just got some new baby chicks added to the farm! We got 6 pullets from Tractor supply again and they're absolutely precious! Second year raising baby chicks and our current grown up babies couldn't be happier with their life here on the goat farm. I want to be able to tell or current baby chicks apart and our tractor supply doesn't sell the little plastic leg ties. They're also black chickens so food coloring and the cattle markers won't show up on their little bodies. Any ideas?
