My husband bought me 1 female that was returned to the pet store when my hamster died. She was pregnant !!!!! Store traded me her 4 babies (which looked like her) for 1 other. It was "outside", tripped on a bump in the lawn, rolled & broke her neck after 1 week. : Meanwhile, the mama (Pippin - crested) was lonely, sulking in corner, no popcorns or noices, like with her pups, so I hunted down a breeder and brought home a female, (Oreo - crested). I visited my breeder later and brought home 2 more (Chloe, tri-texel & Lilly, grey & white teddy) as she said my cage would hold them all (extra large Hagen). That's 4. Meanwhile, I rescued another female (3 years old) as the owner was allergic ?!?, I call her Snowball, she came with 1 Large Hagen. I kept the babies & Pippin in the x-lrg, but Pippin was strutting & growling & chasing everyone, as she did with Oreo. Oreo was also being aggressive to the other babies, chasing & nipping, & she was only 4 weeks older than the other babies. I figure Pippin is dominant, so I removed her to a large cage, and the babies outside for a couple of days together. The 3 babies are now in the x-lrg getting along. I know this won't hold them as adults. Pippin is beside Snowball in a lrg Hagen & when they wheek, they go to the edge to see each other. I clean their cage every day, and they have no room to run. It's almost winter, & too cold for outside runs. I would like to build a C&C home for the babies, or all if possible. Question time .. do I try to introduce all 5, and how? That would decide how big I make the C&C. How do I know if they would use a 2 story? Snowball seems gentle & friendly, purring & easy to pick up. The babies are skittery, how do I calm them. Pippin is skittery, but now likes to be held. She was real wild when I got her. Oreo seems to have kept her dominance, that I feel she learned from Pippin. Should I intro the 2 adults, then the babies, or one adult at a time, starting with Snowball, the friendlier one. They are all different and cute, and I wonder if I should adopt out the ones that don't get along, would it be better for them. The x-large Hagen seems big enough for one piggy, but I'd rather clean only 1 cage, and the bigger the cage, the easier to keep clean. Special note, I have 5 Jack Russell terriers, so a floor or open cage is out of the question. Any help is muchly appreciated .. please. Many thanks.
