I haven't heard back from the vet yet. When I brought Ross in yesterday she said by the looks of things it could be one of three things: malnourishment, bacterial infection, or liver failure. If it were the first two the feeding tube and antibiotics would have saved him so she said she'd try to open him up first chance she got to take a look at his liver. She also said to take the others in at the first sign of odd behavior. Chandler's the thinnest right now but Daisy's the quietest. Usually she spends the day inside her nest box but as soon as she hears her name she crawls out and says hello. she didn't this morning. I have a horrid feeling that she's going to be next.
Saddly, you could have had a bad batch of seed with mold spores in it. And they could have been eating months ago. I had 3 die within days, after the necropsy results came back, that was the COD. It only takes a tiny bit (that they eye cant see) to contaminate an entire bag. I really hope you dont loose anymore.
