Jade may be pregnant, an accidental mating with an angora/Rex cross buck, but she seems overdue to me. She may be having a false pregnancy, very common among rabbits. Or, her mating date may be later than supposed. She spends a lot of time on her nest, getting ready for babies.
Jade replaces Mica, my sable doe, who passed away in March at age seven. A very good old age for a rabbit. In the background of the top photo is Gem, a fawn colored doe and Jade’s new pal.
