these 2 just raised a litter and all went off to live on their own after they were weined and so pretty much straight away after i seperated them and their babies they were mating, and after this mating ritual , 26 days later on august 3rd 2010 ivory, the darker grey, gave birth to 4 babies, in her previous litter there was 7 (1 died a day after they were born), and she raised 3 boys and 3 girls, 5 of which were golden agouti, bumper was a fab dad, i breed gerbils as a hobby, in this litter, which i hope to have a video of soon, i think there will be 2 golden agouti 1 grey agouti, and 1 like bumper, in this video ivory was a little reluctant to be mating but even so she carried on, i hope for people to post nice comments and ask questions! :D
