Can a feather hurt you?

We have some very comfortable couches that are down. So, on occasion a few feathers will work their way out. Zoey, unfortunately, likes to eat them when she finds them. Most of the time I catch her and get it out of her mouth, but I'm sure I've missed a few.... The last two days Zoey has had a stuffy nose and that's it...no other symptoms of being sick, just runny nose. This morning as I put her in the bath to clear out her nose a feather!!! came out!!! pointy end up!!! Somehow a feather got either into her nose or down her throat and back up out her nose. Either way, it was really funny. I didn't take a picture because it was covered in snot, but I'm beginning to wonder if the feather was the cause of her stuffy, runny nose. It hasn't cleared up yet, but maybe it caused a little infection that now can heal since the parasite has been removed. Sorry if that grossed anyone out!
