Some lines just have buck heavy litters, some dont.

The hairless i bred had buck heavy litters, infact most of my litters do to. Just had a litter of 11, with 7 bucks. The litter was reduced down to 4 (does).

Its just one of those things.

I've got one litter of 12 Mice which I have 3 females and the rest are male then another which I have 8 females and 3 male.

I also have Multis which I have 12 which are 8 female and 3 male.

I have one set of Multis 1 male 3 females and they have just gave birth to 20 do not know what sex yet.

The set of Multis that gave me the other 12 have just had another 8.

So I have a room full of babies at the moment :D

Mark that is what the dad is, a black and tan
Your black and tan is related to Marks as well so there's the explanation there!!!!!
It's very a 'in-bred' line as well.

I'm getting buck heavy in most of my litters, be it naked/tans or longhaireds, could it be the temperatures at the moment???
I know temperature affects the sperm so maybe the 'little boy making' wigglies can survive better in the weather we are having??????

I wonder why your multi's are having such small litters????
Are they still very young???
Mine are giving me llitters of over 20 at a time.

I have a colony, 4.7, who had 3 litters at the same time and there were 65 babies.
The parents are now 4-5 months old as they tend not to breed until about 4 months anyway.
Again mine tend to be buck heavy with the multi's as well. it doens't really matter so much with them though as there are so many in a litter there are always enough does.
