whining

Hey guys, So my bunny is an inside boy. I figured he would like some outside time today in the sun, so I put him in his outside hutch (first time he's been out there since I got him during winter) and when I was putting him in, he made this weird little whining sound. And then a few hours...

My rabbit is 18weeks old. Lately his hormones have started to kick in, so he’s starting to grunt at me when I do certain things like picking him up to put him back in his cage, etc. He never lunges or bites though. When my father pets and plays with him, he makes these weird whining noises...
