Well, I added 23 guinea pigs to the grow out pen from the birthing pen. They are about 0.3-0.6 lbs.
I also am starting to process the males that are over 1.3 lbs for the freezer for dog food. Two done so far, a 1.5+ lb male, and a 1.4 lb male. It is so difficult to do. Some of the females in grow out are old enough to be pregnant with their first litters. I am excited.
It is hot and humid, but they seem to be going well.
