i just got a black star pullet a few days ago, and she was fine this morning when i let her out to free range. when i put her back in the coop i noticed one eye was swollen.....there's also a little discharge coming out of the nostril on that side. she is acting fine, so i assume it was a bee sting or possibly a peck from one of the other hens, as she is new. it's not swollen shut, just a little puffier than the other eye. any ideas on what might be going on?
