Started throwing down corn scratch for my birds now that the grass in their run is nill to none. They love it and it keeps them busy all day, but is it just me or are they burying more than they are eating? Peck, Peck, Scratch. "Hey where'd it go?" Lol. I also have the feeder for my laying mash off the ground and a few of my silkies will hike their legs up and try to scratch at it. Is this a normal chicken behaviour. Not a concern or problem at all, just fun to watch and thought it would be worth the share.
