This started seven days ago when we were about to leave on vacation. Two of my chickens had cloudy eyes, it almost seemed white. We left my older cousin in charge of the chickens while we were gone on our five day vacation. When we came back, two chickens had died and eight more were sick. Three had healed since then and two died. I was wondering if this could be caused by dehydration. It's the middle of the dry season in the Philippines ans the chickens usually drink from the river that runs through our land. The river is dry and I don't know if my cousin gave them water. The symptoms are cloudy eyes, swollen faces and weakness. If anyone knows what this is or how to treat it please help.
