Hi My 3 11wk chicks have been raised on hay bedding, the other day I thought they were old enough to grow up a bit more. So I cleaned out thier broody coup and changed it to soft wood shavings, then let them back in to thier run. They noticed the few messy bits of shavings I had dropped and to my horror immediately started to eat them!!! I started hard clucking and pushing them away from the shavings but it was like catching water, so I buzzed off and got Molly (Bird Mum) to see if she would tell them off, nope, she just went bum up and got stuck into thier food. After an age of tapping them off when they tried to pick a bit up and fed them feed instead.... I had to admit defeat and give up. Locked them out of the pen and had to thouroughly clean out the clean coup and revert back to hay. Advise on changing much appreciated.
