I have these two chickens , a pullet and cockerel about 4 months of old. I keep them in this cage in my little backyard on second floor( the little courtyard has tiling floor and not soil.) I keep the chickens cage door open so that they can roam around the yard whenever they want but they just stay in and keep their beeks open, furiously gasping in the heat. The atmosphere here is about at 40+ degree C all day but cools at night. I fear that my chickens may die of the heat because one of them is a golden campine from cold origins and might not be able to make it.I the yard stays in intense sunlight from 10:00 am in morning to 5:30 pm in evening although the about half of the yard is in shade by 3:00 p.m. I keep the floor cool by spraying water over it twice or thrice during the sunlight. My chickens look thin now and I can't think of anything to cool them. They have water and food all day long but I haven't covered the cage floor(wooden) with anything like sand or pine shavings(one of them got sick when I used pine shavings when they were chicks). So any ideas how I can keep them cool because I can't move them inside the house as it takes so much space and smells so ...chicken-like... Please. Any ideas would be appreciated.
