So I have a standard hooded female, two dumbo females (a beige and a black spotted), and a standard beige male. Before they would all hang out in or on top of the igloo together. I've noticed the black dumbo female seems chubbier than her sister. I've been really hoping she's pregnant but I think it might be wishful thinking. I've only had the dumbos for a week and the male for five days. Two days ago I noticed the black dumbo digging next to the water bottle. Since then I've seen her lay outside the igloo and the females are curled up next to her while the male is in the opposite corner. Then today the two other females are in one corner, the male in another corner, and the black dumbo in the igloo by herself. I don't know if this is them just being comfy now and don't feel the need to be in the igloo most of the time or if they are giving her space because she might be pregnant and nesting? Also if she is pregnant will the male know it's not his and kill the babies? Since they've been together for a bit will he think they are his?
