Okay so I received the final report from the lab, and discussed with the vet.
I will attach the report but to summarize:
one of two of the pullets had large nematodes, so round worms present in her intestine. As well as acute bacterial infection present in many organs. Awaiting the culture results for what type of bacteria.
The other hen died of malnutrition although showed similar symptoms, she showed no signs of round worm or infection. The recommendation from the lab is to review flock nutrition- however they have access to all flock feed, free fed and multiple feed stations, fresh water in a heated nipple waterer...I just dont know what else I can do to ensure adequate nutrition.
Will be deworming while we await culture results.
The vet said the 4 that are still fairly stagnant in their recovery will likely not recover and went on about the commercialized breeds are less resilient and thus it would be best to humanely euthanize them....ugh my heart just hurts. They are still eating and drinking, they try to move around a bit but I am on the fence.
Anyways hope this is helpful, I can post a brief update about what the culture comes back as and what treatment we end up with. Thanks for everyone's input and care for my little flock
