Pregnancy Rescued Pregnant Guinea pigs

[tall]

Hi! I recently adopted 4 pregnant guinea pigs(they were all pregnant and all sexed by the vet) that had been rescued from a breeding situation. They all looked healthy, nice fur, no bald spots. The vet said they seem to have all been pregnant before based on their nipples. I put ivermectin on all of them when I got them based on vet's instructions.
They now live by me and have a warmed shed in my yard with unlimited access to water and hay. I let them out during the day to graze in my walled garden on grass. I also supplement vitamin C.
Two of them died suddenly. They were a little lethargic and didn't go out to graze in the morning, I thought maybe they felt cold outside. Their shed is heated and very nice. When I came later, they were both dead.
My vet is unsure what caused this. Any ideas?

There's really no way to tell. And guinea pigs handle cold much better than heat, so unless it was freezing outside, the temperature probably didn't have anything to do with it.

They could have been incubating some illness before you got them, or possibly have been bitten by a spider in the shed or in the yard.

I'm so sorry you lost them, but thank you for taking them all in.

And just as a reminder, you do know that you have to separate any male pups from all the females at 21 days of age, don't you?

Yes, the vet mentioned that. I have two ready large cages for the male pups once their at 3 weeks.

Is possible that because they are only getting hay, grass, and vegetables(lettuce, bell peppers, and cucumbers) that they have calcium deficiency?

Maybe, maybe not. But it's never a bad idea to supplement a pregnant sow with some high calcium veggies. Vitamin C, too. The babies take a lot out of the sow's body.
