Jay, if you read the link I provided for you the answers are in it. We can't diagnose your rats and tell you if they are sick or not or will get sick. That's a vet's job. You've had losses across the board it seems lately and I'm at a loss to tell you anything more than I have already. Something is up in your colony and you need to start addressing it. Feeders or not, it's not fair to animals to die for no good reason.
The last time you posted about rats dying on Aug 10th I responded with this post...
http://www.ball-pythons.net/forums/s...ad.php?t=72792If you are having die offs in various littes from various females at various ages I'd be looking at your husbandry first. It's not unusual to get crap rats from a pet store but you don't usually see problems across the board like that (it's more individual animals). Look into how you are keeping them, breeding them, feeding them, etc.
Getting "furious" because a breeding animal doesn't perform as expected is counter productive. They are living creatures, not production lines. They will do as best they can depending on their genetics, their abilities, how they are cared for, etc. It's not personal.
My thoughts haven't changed much Jay. If you have sick and dying rats, from adult breeders down to new pinks then something is going on with the husbandry choices you are making. I'd think you'd be wise to address it as quickly as possible.
If that rat is suffering either seek vet care or humanely euthanize it. It's hard but you have to make these calls for the animal's sake.
