I have a flock of six & seven week olds, plus 2 one year old hens & 2 two week old chicks. I was doing some yard work and raked up a bounty of worms. I was so excited to feed them, I went in the pen & dropped them on the ground in several places . They did not even know what to do with them, kept looking at me like they were saying "Ok mom, where are the treats?" I thought maybe the teenagers didn't know they were food, so I tossed them to the adults. No dice. The only ones who appeared to have any interest were the chicks, but I think they thought they were playthings rather than food. Lucky worms..
