Definitely better safe than sorry. Such a shame you've had such a bad experience. Hope the vets have identified the cause(s) of the problem and you can get them more comfortable

The way I have read your posts is that you were concerned about this breeder as your guineas were covered in wounds when they arrived and you suspect they had been bullied . The way I read your posts, it seems you suspect they may have had a fungal infection which the breeder was unaware of .
I agree you should buy from reputable breeders but I did all I could to ensure I was.
