I noticed just today while I was filling his water bucket that he was doing this weird, long 'yawn' looking thing with his mouth, but he was curling his tongue around in a weird way. At first I just thought he had to yawn really bad, bu he kept doing it! I've never seen him do this, and I checked him over and he seemed fine to me. He proceeded to eat and drink afterwards, but while he was just chilling in his stall, he would occasionally do it at random times. He wasn't like freaking out, he seemed pretty chill, but it was weird!
Should I be worried? Or us he just being goofy?
I was scared that he was choking, but he was breathing normally, eating and drinking normally afterward so I just don't know.
Haven't noticed it again since this afternoon though.
