Ok, so the quick back story is that I lost 2 of my 2 year old black bantam Ameraucana hens last week. They died within 24 hours of each other - that's the weird part. NO signs of any illness or injury. They were COMPLETELY normal and then DROPPED DEAD within a few hours of being seen and being 100% normal. I just got preliminary necropsy results back, and they both died of the same thing - acute hemorrhage caused by Fatty Liver syndrome. BOTH of them. After the second one died I carefully inspected the coop, and what I found was 3 small white hairy mushrooms growing in the corner of the same nest box that I found the first hen in. This is actually a tractor that has 6 nest boxes built into one wall with doors that open on the outside. When it rains hard (sideways like it has been) they leak in the corners, I am guessing this is how/why this happened. Also, it was one of the higher nest boxes that is hard to see into the corner of, so I didn't see the mushrooms until they grew tall enough to peek over the edge. If it wasn't the mushrooms (I'm thinking they could've caused the bleed itself, but maybe not the fatty liver??) I don't know what to do about the others. These particular birds get no fatty treats AT ALL. They get a combo of Flock Raiser and Layena crumble, and veggie scraps. No corn, no BOSS, no seeds. HOW is this diet too fatty?? Oh, and they have 24/7 access to the ground, but this "tractor" is too heavy to move so it's all barkdust and dirt in their run.
