Baldwins

Baldwins are completely bald with absolutely no hair at all or
very minimal on their feet, but they do not come out like that when
they are born like the skinny pigs do. They are born compeletely
haired like a regular haired guinea pig. After just a few days of
their birth from 2-5 days old their hair falls out from the head to
their bottoms until they are completely bald at around 2 months of
age or so.  

Skinny pigs and baldwin guinea pigs seem to be the consequence
of different separate recessive mutations in one gene each so the
conditions only occurs in the homozygous state. The skinny and
baldwin genes do not appear to be related to each other at all
and they do not go together. When you breed a skinny pig to a
baldwin you will only produce haired babies in the first generation,
so they are defiantly genetically different from one another.

Baldwins are said to lack a thymus gland, and are thought to have
anatomical abnormality difficulties, and reproductive problems
specifically with the males(there are only a few with these
problems but it is very rare).There is some thought though that if
Baldwin's seem to be hardier, sufficient to develop, and
successfully breed, than their immune systems seems to perhaps
be made more capable with each generation.

We have now been producing very hardy Baldwins in our caviary
that thrive and are just as healthy as our skinny pigs.  Carol Miller
the originator of Baldwins also does not believe this to be true as
the Baldwins have come a long way and are producing very hardy
lines.

The baldwins have a rubbery texture to their skin when you touch
them.

When Breeding Baldwins:
Same as the skinnies

Baldwin X Baldwin
When you breed two hairless Baldwins together, 100% of their
babies will all be Baldwins(with hair that falls out and become
totally hairless).

Baldwin X Baldwin Gene Carrier
There is a 50-75% or about half chance that the babies bred by a
Baldwin to a haired Baldwin gene carrier, will have hairless
Baldwin babies.  The rest will just be baldwin gene carriers. You
will know which ones are the true baldwins when their hair starts
falling off.  

Baldwin Gene Carrier  X Baldwin Gene Carrier
There is only a 25% chance that 1 or so baldwin babies will be
born in these litters.  You may have 1 or so carriers from this
breeding too.  

Baldwin X Regular haired breed guinea pig(not a gene
carrier of baldwin)
None of them will be a hairless baldwin.  There is a chance that
most of the babies will be baldwin gene carriers which can then be
bred back to the Baldwin.

Baldwin Gene Carrier X Regular haired breed guinea
pig(not a gene carrier of baldwin)
There is no chance a baldwin pup will be born from a Baldwin
gene Carrier bred to a regular haired guinea pig(not a gene
carrier).

Baldwin X Skinny Pig(breeding not recommend)
None of the babies will be hairless like the Baldwins or Skinny
Pigs. They will all have hair and look like a regular haired guinea
pig, but 50% of the babies will carry either the gene for Baldwins
or Skinny Pigs and you won't know which ones they are.

All the Baldwins born in the litters will all have hair and look like a
regular haired guinea pig, and then their hair falls out until they
are completely bald.  You won't know which babies will be the true
Baldwin gene carriers until you breed them.
