I went to the store today and picked up some worms for my 4 wk old chicks. At first I gave them the whole worm (they were tiny worms) because I thought they would just tear them up with their beak. They just grabbed the worm and ran around with them and didn't try to eat it or anything. Then I broke the worms into smaller pieces and they ate some of the pieces but left some. I thought they would have loved them and fought over them like they do for bugs. Are they just too young for worms?
