I’m not sure how far along I have never had pregnant guinea pigs I do not think you can prevent it just monitor the mom and make sure she is staying healthy
I would say if you felt kicking in the right place there is a good chance there are some alive if you have one dead that can lead to others dying as well
I’m so sorry you really tried to do the best I know people who would have just killed the chicken at the sight of a lump or just have done nothing trying to improve her quality of life was a great thing to do no matter what I am so sorry and really wish things would have worked out
I have a Silkie who I have to put out of the nesting box and lock her out if the coop I’ve tried putting rocks in all the nesting boxes but she sits right on them I haven’t tried the crate method yet but want to try it before winter becomes she will go broody for months so I have to lock her out...
