I just recently purchased three rabbits 1 buck and 2 does and one of my does, Calypso, was fine the day she came home with me but the next day when I went in to feed, water and spend time with the rabbits she was apprehensive. When I reach in the pen she huffs and everywhere I move my hand she watches and follows it. If I try to pet her back she jumps and turns immediately to face my hand. I'm hoping she'll calm down but she was not like this the day she came in. I thought I'd give her a couple days to calm down and get used to her surroundings but she's not calming down at all. She's still apprehensive and jumpy, I can't even reach in to put the food bowl down for her. Any idea why her behavior changed literally overnight?
