I have a 16 week BO and 2 days ago she had what looked like a "wet" or "oily" looking neck. At first I thought she just got wet from the dew, but then it never dried. She is acting normal, eatting, drinking, good poops. Eyes look a little watery, but not too bad. Beak looks normal. Took her out of the pen/coop, but I have searched all over and can't find anything about this. Any help would be great. She is eatting layer crumbles, scratch, oyster shells, bugs etc! Thank you all.
