My 16 month old Light Braham is breathing very hard and is very lethargic. She is not eating or drinking. She did have one normal poo today. I am giving her watered down gatorade via eye dropper, but she won't take much. She is my dominant girl and best layer in my flock of 6 hens (4 are 16 months and 2 are 4 months). Any help is appreciated!!
