I was watching my chicks who just turned 3 weeks on Saturday. One of the Marans took a dust bath in the pine shavings and as a result the loose shavings covered her feathers. Three of the other chicks came running over and started pecking the shavings off like they were bugs. I don't think it bothered the peckee because she acted like she didn't even notice, but I'm worried that this behavior of pecking each other will escalate. Tonite Im picking up a few more boxes to expand their area to 48 square feet (I have 49 chicks) but they also use the vertical space and will roost on the box edges. Ive hung large shiny bolts and nuts from string to give them something to peck at other than each other . Anyone else have this happen? Should I be worried?
