My mom and I are testing our hens to see if they are laying and out of the molt or are too old to lay and we put them in a brooder coop and wait 3 days to see if they lay at that point they are tossed into the non layer and rooster pen and she did lay today so we put green zip ties on both legs to mark they are good hens and my moms hand felt something sharp and we looked and she had a spur! i told mom could it be an extra toe or in grown toe? cause its right where a spur would be and its only on the one leg and i told her maybe when they get older they grow them??
