Sorry to disagree with everyone, but I would not put him back in the cage with Wheezy. This is information I found on Seagull's Guinea Pig Condominium and it is also the exact same information I got from my vet when I had a pregnant sow and a neutered boar......
It is not necessary to remove the male during the pregnancy, though it is generally a good idea to do so in the last week before birth, since the female will come into season again within an hour after having her litter. Sometimes, however, the male can be considered a stressor in the final days of pregnancy, and you may need to separate them if he and the sow are not getting along. If you have multiple, pregnant sows housed together, then it is extremely important that they be separated during their gestation. The birth of one sow's litter can actually induce labor in the other sow, which can lead to a premature birth even if they were impregnated at roughly the same time.
