Wow, that is a huge loss and setback. I'm very sorry for all that happened.
How did the formaldehyde get into the soybeans? I'm no soybean expert, but isn't formaldehyde use to preserve dead things? I hope they weren't using it as a cheap preservative.
Its terrible since this is one of the things you can't plan for. My 1 female rat just dropped 11 babies, not sure who the father is so we will see. If you need any help with females I will gladly help out.
