I live in Texas and it has been in the 100's for what has seemed like all summer. I have noticed my girls panting with their mouths open in the evenings when I get home from work. I just figured that this was how they kept themselves cool. I always made sure they had plenty of water and shade throughout the day. Yesterday I went out to feed them and noticed was of my girls was laying there dead. I feel so bad and think that this has to be tied to the heat. I promply got on here and started researching what I should do to prevent the others from following the same path. I put electrolytes in their water and also some ice cubes to hopefully keep it cooler throughout the day. I also put a fan in the corner to hopefully create tsome airflow since we have not had much of a breeze. I did notice that one hen had bubble eye and a slight sneeze and another that also sneezed on occasion. Am I right in thinking that the panting possibly lead to a respiratory issue? If so, what can I do for this and are the hens respiratory problems contagious to the others around them? Thanks, any help is appreciated.
