I'm in Michigan and I have two 2-year old RIRs. They have a cozy run and a 3'x4' coop with straw. I've been feeding them Layena and I have a 40W lamp in the coop during the day until 8pmish to keep them laying. Tonight, I tucked them in and rewatered them, and harvested an egg coated in a slimy icky coating. It was colorless and odorless. They don't have a laying box, so they lay in a little nest in the straw and there are often specks of poo on the eggs. Any idea what this coating could be? I'm familiar with bloom, and that always seems like a thin coating that evaporates immediately. This was thick and gooey but without color or odor. Any ideas?
