Ok, after seeing the parents, I would tend to agree that there is more Nicaraguan influence rather than Argentine. Not seeing much Argie in the mom at all and the dad looks pure Nic to me. Could be some CA influence in the mom, so it sounds like most people are seeing the same things - mostly Nicaraguan with some Central American influence.

I also agree with H.o.F.R. in that the babies may be showing some selectively bred traits. Both the female and the male are very nice. The male seems to display some anerythristic traits as well, although that may have to be proven by breeding him later on.

I am not aware of Nics generally having smaller litters, although it is possible since they are considered one of the smaller localities. As such, they may not have the larger litter sizes that Colombians or BCCs are known for. On the other hand, this litter could have been a bit smaller if it was the dam's first. Usually a first time mom will only have 10-20 babies in her first litter.
