My 9 week old polish/silkie mutt is acting very strangely. When i'm just looking at her walking around she's fine. She eats, drinks, and pecks around at the ground like the others. But when I pick her up she opens her beak a little (maybe panting but it sounds like she's breathing through her nose) and when she breathes it sounds like she has mucus in her nose. Then when I put her down, she closes her beak and acts like nothing ever happened and her breathing doesnt sound wierd. I'm stumped with this one. If she is sick I want to quarentine her so the rest of them dont get sick. She just doesnt look sick at all. The only other thing im noticing is half runny light brown poo but my silkie had the same thing and people said it was normal.
