Possible lameness

No, I dont think so. The grandparents (the original outcrossing) are perfectly fine. I've spent a lot of time with the parents too, and the lameness (now that I've seen it) is VERY obvious, they have never shown any bit of it.

I dont think its possible that they have it, but it could definitely be a genetic thing, but with this litter the females are nursing now, we will see how they are when they wean in a few weeks.

I would personally cull the ones with the problems unless you are able to trace it back the linage 100% and check for further deformities from the original parents. Also is it possible it could be something like an inner ear infection that is causing the imbalance problems?

We try to add in new blood at least 2-3 times per year and seems to help enough to keep them from becoming to inbreed at least to the point of undersized babies, litters or deformities.

Good luck.

Once you see the video, it's very clear it is not a balance problem. More of weak muscles, or motor skills problem.

This is only the second generation from an original outcrossed pairing. I do not think this is the product of a mutation of any sort.

They are feeders anyways, one way or another the original group will be fed off (they were already on that list).

Good chance it is just a litter thing then.

I have to admit, they are pretty cute to watch. You feel so sorry for them you love em. :oops:

More handicapped rats today. 3 more from a different breeding group. So far the common denominator is the original father rat of both of these groups.

Will have to do more breeding to know for sure.
