It is not right to call someone out like that.. this is his 4th post and he is a new cham owner and a person new to the hobby and he is treated like this?? un called for. your a senior member how about setting a example.....with that said.
hey man its all good. dont stress to much this is a fun rewarding hobby. now take a pic of the habitat and lets see what going on over there. the head bobbing thing is a sexual suggestion that comes later. i believe he is leaf walking. if he is lifting his head it could also that he is dominate and claiming his area. give his some small crickets dusted accordingly an admire from a far...not all chams will eat infront of you. look for scat on the floor thats a good indication he is eating. give it time and be patient and enjoy that little guy it just gets better......now lets see that setup buddy.
