What is wrong with my poor little bunny?

I just got back from a two week holiday, to find that my 4 year old male bunny seems to have something wrong. First of all, I noticed that he seems to have possibly cut his nose, as on the side of it there is a small, single scab. So perhaps he scratched it accidentally or something, I am not sure. But he is still breathing fine, grooms the area as he would normally and is not showing any pain or discomfort, even when the area is touched.

But, I also noticed that on his left ear, at the bottom, at the rim of his ear, it seems to be a bit “crusty”, with a few small, dark scabs, which I think may be causing some minor discomfort, but I am not sure. And me, being a worrier, am just scared that maybe there is something wrong with my poor rabbit? First of all I thought that maybe he is starting to get VHD, due to the scab on his nose… but I checked his “private area”, and it seems completely normal. So, I have ruled that out. I also thought that maybe it could be ear mites? But the inside of his ear is clear and normal.

I am just worried for him, I’m scarethat there is maybe something wrong with him? It’s just he hasn’t been ill before. So, I am just concerned about the scab/crustiness on his nose, and the rim of his ear? Note that his other ear is fine, so perhaps his claws are too long and need to be clipped, could he have accidentally scratched himself? What do you guys think? Thanks in advance!

Plus, I know this is kinda weird, but there is a leaf stuck to the bottom of his back foot, and it won’t come off easily, any tips on getting it off without pulling out a load of fur?

Sorry for how long it turned out…
