Ok so long story short. My rabbit gave birth to a litter of 4 healthy babies on 2/22/23. Everything went well and babies and mom are healthy. But when the babies were about 3 weeks old I noticed my bun becoming big again and low and beyond she is pregnant and babies are moving and kicking in her belly. Her first litter is about 4 weeks old now. She seems like she’s due any day but hasn’t nested yet. Could this be because her first litter is still with her? Should I remove them now? I’m lost because once I felt her first litter moving and kicking she gave birth a week later but still nothing.
