HELP! My Flock is dropping like stones!! PLEASE!! HELP!!!

[tribble]

I have 5 copper maran x astroloupe crosses mixed with some birds whos breed I dont know. In the past few weeks I have found 5 of my birds dead!!! I notice no symptoms in them except one bird (she was having issues walking then she moved in the coop for the night and i found her in the morning dehydrated). All of them, but the one with the walking issue, seemed healthy, no injury or anything wrong until I found them dead.
I have found one with its head stuffed in a corner, one under the waterer, one just in the doors of my coop, one in the egg boxes, and the one with the leg issue in the middle of the coop. I am not sure what is going on!!!!!!!!

If you have an idea I would be thankful to hear it, for I am clueless and confused!!

Thank you for taking the time to read this and sharing your knowledge to a fellow chicken owner with a problem!! Thanks

How old are they? There has to be some symptoms,(unless they all had heart attacks,which is unlikely). Check for runny/watery poop,impacted crops,vent area,any signs or prolapse vent,new feed,algae in water,dead rotting mice,frogs,etc. How high are the temperatures,had they been eating/drinking,any discharge from eyes/nostrils?
