i found 2 of my chickens dead , all of them have blue/purple head and legs kinda strange , the next day i found my rooster with blue/purple head , then in the evening his head was bright red and he seems fine.
now he is very lazy and weak , always sleeping / sitting , been like that for 10 days or so
is there anything i should give him? antibiotics?
my neighbor did burn some wood / junk about 800 ft from my chicken , would that be the reason my 2 chicken died?
