I heard Thumper digging in her cage this morning, and didn't think anything of it. Tonight, she's actively nesting AND pulling fur! The catch is, she's only 4 1/2 months old, and has never been bred! She's been on her own since she was 8 weeks old, and has never been in with any of our bucks. She is across the isle from our new buck in the rabbitry though, he's only been in there for 2 weeks now.
What does this mean?
