So I got some play sand yesterday and while they were out free ranging, I put some in half the run. They refused to return to the run until the last possible minute, and when they did, they treated the sand as if the mere sight of it there would have them burst into chicken nuggets. They would all get up on one of the run roosts, and then jump to the ramp, and finally walk into the coop. I figured this morning, they would come out and just finally walk on it. But nooooo! Halfway down the ramp, and then fly to the nearest sand-free spot. Their food and water are all on the sand side! I took some scratch and threw it into the sand, and now they are all standing around the sand as if it's a pool of acid, and stretching their necks as far as they can to get what little scratch is possible to reach I'm guessing this is normal for sand users for a bit, and that they'll finally get used to it?
