So I noticed this morning that one of my Mumma Hens is squeaking when she breathes! She's wondering around, pecking and eating normally though. Her chickies seem okay as do all the other chickens... Anyone have any idea what it might be? I'm thinking I should seperate her from her babies but I really hate the thought of that! But I don't want them to get sick either if it could be contagious. I have some stuff to treat respiratory infections so wondering if I should try that...
