I am very new to chickens. I have 4 Rhode Island Reds. I have only had them for almost a month now. One of them has acted like she has laryngitis. She acted fine as far as I know just didn't have a voice. They are about a year old I believe. Only one have been laying eggs. This morning my girl with laryngitis is just sitting on the ground not moving with her head down. She is still breathing. Don't know what to do. All the others still act fine as far as I can tell for not knowing anything. Help please?? Thank you!!!
