It's a roller-coaster here :D and party didn't even started properly!

Bunny?
Really? Awwwwwwwww, love them, but they are buggers and serious harm, especially during the winter time.
Hm, maybe try out with garlic, rare animals are enjoying it's smell, soak it in water and spray it on the plants, or sprinkle it on if you're using a powder. They will try maybe few more times, but probably will give up.

Egg shells are awesome, just throw them away on air in several weeks you are having high quality supplement!
