what's this behavior?

[Hunter911]

My eldest goat Walter who is 3, just started doing this. I don't know if it is him playing, or a challenge. I get in the pen with them and he will do this weird lapping thing at my hand with his tongue and mouth while cackling with his voice and sometimes gets his front foot pawing. A little hard to explain. I let him carry it through the other day to see if he was trying to bite or??? He mouthed my hand a little but never bit down. I tried to attach a video but it will not let me. What do you all think?



Thank you
