Last Sat, I lost one of my oldest hens. She was a hatchery Silver-laced Wyandotte and was 4 1/2 yr old. She seemed fine when I let the chickens out at 6:30 and I saw her eating the wet feed with supplements that I give them at around 7. 2 hours later, Monet found her dead in the middle of the yard. Since it was Sat, I soaped her up, bagged her, and kept her in a cooler with ice until Mon. FedEx was open on Mon but I didn't realize until I got there that they were not doing any pickups that day. I feel sorry for the tech who had to open that box on Wed afternoon. I asked them to test for all kinds of things. The prelim report came in last night. The result was death due to intra-abdominal hemorrhage secondary to liver rupture (Fatty liver hemorrhagic syndrome). They said that she was an over-conditioned hen with lots of fat. I weighed her before packing her up and she weighed 7 lb. I guess that I killed her with kindness and too many treats. This is not the first older hen that I have lost to this. I have been giving my flock some dietary supplements that are supposed to help with liver health such as mild thistle seed powder, kelp powder, alfalfa powder, etc. I do give my flock sprouted BOSS but not very much of it. The grandkids love to feed their leftovers to the girls so I guess I should curtail that. Does anyone have experience with counteracting this condition?
