Worried !!!

I was just outside in the garden, checking on the rabbits, when I noticed theo just sitting in the flower bed, with his chin resting on the paving slab

When I approached him, he didn't sit up as he would normally, when I touched him, he just sat there in the same position, which is really unusual, he is usually bounding away

I picked him up without a struggle, now I was getting really worried as he never lets me pick him up without a fuss

Putting him down he just sat there, but within a few mins he perked up and hopped away

I hope he is ok, and is not sick
