Hi there, I am a first time chicken owner. I received four hens two days ago (they all lived together in their previous home). The hens are already laying eggs and are about a year old. I noticed that one of them has a watery, bubbly eye, with feathers coming away. Since it's literally my first week of owning chickens, I have no idea what to do... FYI: we wiped her eye clean with warm water to get the crusty feathers off. I'm worried what to do with the other birds too. I've attached a picture. Any advice, suggestions, answers would be greatly appreciated! For reference, attached is the other eye which looks fine.
