My little brother (5) bought a chick a few weeks ago and it is a black jersey giant. I have a couple of those along with about 25 other breeds in a big flock. Anyways, i usually mark with a leg band when i have two of the same breed, and even then i can usually tell them apart, but he can't. i was wondering if anyone had a way to mark them that they stand out. My dad suggested a colorful spray paint on their tail feathers, but i was worried other would try to eat it. This may seem weird, but if anyone has any suggestion, i would appreciate it. Thanks!
