I'm a newbie. I have 7 RIR hens that are six plus months old, have been laying for a couple of weeks. I'm getting 2 to 3 eggs a day. I had a young man raise them from peeps till now. When I got them they were on starter and he was also feeding them some cracked corn. I've switched them to laying pellets. They don't eat very much of it, but they have a good sized yard and seem to be eating lots of bugs, grubs, etc. They look and act very healthy. Today I decided to try to give them some of the pellets mushed up a bit with some homemade yogurt. They really seemed to like it. Then, one of them began to wipe her beak off in the dirt. Then another one and another. One used a foot to scratch at her beak. It was like something was sticking on their beaks that they weren't comfortable with. Then they all seemed to be finished with eating this even though they had not finished what I put out (about a cup and a half of pellets). Is this normal behavior?
