Ok, thanks for the update. If your last chick dies or if you get more chicks and they die, it would be best to contact your local extension office or your state Department of Agriculture and find out how to go about sending a bird off for necropsy.When I got home from work the little chick that I have left was just sitting there looking at me al sad and lonely. It breaks my heart. I was able to check my vents real quick before heading out to get dinner with the fam, nothing clean as a whistle. I wasn’t able to get pictures of the brooder and the chick as I was only home for a brief moment but will take some when I get home.
Also a college veterinary school might be able to assist with a necropsy as well.
