I just found my favorite Delaware hen, Henrietta, lying dead on the coop floor. I checked her over and saw no obvious signs like egg bound or damage. However I noticed yesterday she kept sitting down which seems to be a usual sign something isn't quite right, but then she got up and foraged with the others and seemed fine last night. Only other thing I noticed was that the feathers on her head and neck were very very yellow. We've done nothing different except that I am slowly changing their grain from store bought to homemade gluten free grains as of 3 days ago. We want to drive her up to Tulare tomorrow for a necropsy. Can someone please give me the address, name of institution, & phone number for there? This will be the first time we'd like to use a free California University necropsy service and we only live an hour south of Tulare. Also I bagged her and put her in a refrigerator. Is that the right thing to do with her? Thanks in advance for help anyone can offer me tonight.
