Hi Christina! a litter of rosies is born usually in about an hour. I've watched the entire process and photographed some of it. It starts with contractions and "waves" of abdomen movement.
Eventually the tail starts to move from side to side and the babies are pushed out one at a time.
Mother rosies will typically move around while this is going on, and babies are typically dumped in different places in the cage as they move around.
It's very important to remove any water bowls, as mothers will accidentally dropped them in the water and they usually drown. I have a friend in Las Vegas that has had that happen a couple of times.
Here's a pic of the last baby of a litter coming out
Below a couple pics of my male Limburg albino Rosy, showing the bright orange and red eye, not found in the whitewaters, which have dark eyes
There's quite a story to me getting these.
They crossed North America three times in the dead of winter, were seized by the Cdn Government, sent to the Toronto zoo under temporary custody of the crown, then returned to USF&W in Atlanta GA, who inturn forwarded them back to the breeder in San Diego. (they were home for Christmas LOL)
A total of 3 CITES permits per produced for these,two from Washington DC and one from the Canadian government (to send them back), all simply because the original CITES simply missed getting stamped by USF&W in Atlanta, before coming to Toronto.(Delta Screwed up& boarded them too soon)
From the time I ordered them to the time I took legal custody was about one year...
Stuff like this is why I have no hair
Needless to say, It will be a happy day when I produce Limburgs... Hopefully in 05
