Hi guys, This morning I found one of my chickens dead in my coop. I suspected a respiratory illness from the moment I observed her batch in the coop and apart from adding apple cider vinegar to the water as a preventative and watchful waiting I didn't do too much in the treatment of the bird. When I placed the bird outside on a bale of straw I noticed a milky fluid discharge from her beak. Rigor had set in but there was some warmth near her breast bone. I'm confused by the milky discharge. Can anyone comment about the potential origins of this fluid. Is it related to respiratory illness? Sinus fluid? Decomposition of the body? (It was only 11 hours since I'd last checked the hens). Thanks for any feedback. This is very upsetting for me as it is the first bird that's died under my care. Searching for answers.
