I am not sure what happened. I closed up the coop last night and all was well and this morning when I opened up the coop my 3 hens came out and I found my rooster dead. Nobody had any evident signs of being sick. Eyes were clear, energetic, eating and drinking normal. The only diff I possibly noticed was the poo wasn't as solid and more of an orangy brown. I'm now worried about my 3 hens. Aside from being playful and eating/drinking good I have noticed they have all been spending more time inside the coop during the day. Its in the 50's so I know it isn't because they are freezing. They come out and play while I'm outside but they come off as lazy when I look out my window and see them casually just sitting in the coop. I clean the coop out once a week and use pine shavings as well.I've never known chickens to spend so much time in a coop for such long periods during the day. This is the first bunch I've ever witnessed doing this. I just worry that whatever was wrong with my roo may be wrong with my hens. I would hate to lose any others as I'm extremely attached to these guys.coccidiosis had crossed my mind but I have seen no blood in their poo. And like I said it was sudden. I didn't have a clue anything was amiss with them since everyone was eating, drinking and being super playful. Anything helpful would be appreciated.
