my neighbor has chickens as do i , she lives across the road , and some of her chickens are acting funny and we were wondering if it could be due to the recent snow ice and freezes , she has had a couple die for some odd reason but thinking it is do to to many roosters , but the question is , what will cause the area around the eyes to swell cause the eyes to close and you can hear like a rattleing noise when the chicken breathes and have a snotty nose also the chicken will hold its mouth open and stretch its neck out like if it were trying to spit something out and make a caw sound like a crow does ? what is wrong with her chickens, is it sick or what and if so , what antibiotic does she need to give them ... my birds seem ok but i also have heat lights on them and all , what does she need to do , any opinions
