Well a mate of mine near a year ago had a litter, Which all lended up catching it at some point within the first 12/15 weeks out of 6 only two died,
And the rest all survied,
The only one i see now is the one he kept back, and he is a great little worker, nothing at all wrong with him...
One thing tho i do think it stunted there growth or something, all were suppose to be 22ish, and the i kepted back only got to 16tts,
And the tallest and biggest in the litter got to 19/20tts...
