help I have a coop and pen with about 10 chickens in it with two ducks. I went to check on them about mid afternoon yesterday and one of my silkie roosters was in the corner of the pen with his eyes shut. I opened it up to check on him and he was pretty much lifeless all he would do is open his eyes. I checked on him through out the rest of the day and he never moved. went out today and he was dead in the spot he was at last night. I was counting and looking over my other chickens and noticed one of my cochin/silkie hens wasn't out, opened the coop and she was in her nesting box dead also. it has been hot the past couple days around 100 or so. is it just the heat or do they have a diseases. they are given fresh water through out the day when it is that hot out. please help before I loose anymore. one day they are fine the next dead.
