I will do my best to answer these questions. No not at the same time, one died on Friday night Saturday morning, not sure exactly this one may have been left outside over night. The other one died in the coop last night. I did not see any signs of stress or marks. I believe the water supply is good, they had plenty of water. They have plenty of shade as their runs are in the woods. and the temperature has been between 45 and 80. Haven't tried giving more food at this time. What I was doing was taking the food away during the day and giving it back at night until last night which was the first night without food in the coop. I hope this helps. And thanks for any input.
