Rabbit query about his eating habits!? Could really use some help!?

So me and my bf went away for a few weeks, got back Saturday just gone. Straight away when we got home we knew bunny (neutered) had missed us! He's settled down now but last few days I've noticed when I go to give him a bit of carrot, he comes running over and latches on to it like he hasn't seen food in for ever! (but he has got a constant supply of dry food in his hutch, I am positive he is eating this aswell) so after he's eaten most of the carrot out my hand I usually hand it over for him to finish off on his own, instead he's now dropping it and whether or not it's a case he can't see it, he goes into a panic running round my legs until I pick it up and show it to him and again it's another desperate lunge to get to it! When he does have the carrot he still likes to parade about with it. The girl that looked after him is a very close friend's daughter and has looked after him a few times now, so I know she would tell me if there was a problem or not but I will be double checking today! In the mean time if any one knows why he is doing this or has any idea I would really appreciate some feed back!! TIA X
