Hi. I have 5 beautiful 6 week old Plymouth Rocks. Chimey has what I perceive as swelling around just one eye. No known injury and nothing caught in the eye. I have been washing it out with water which hasn't seemed to make a difference. She is eating, drinking and playing normally. No one is picking on her. I was close to panic after 2 days until her ears started developing further and I started wondering if this was perhaps the "perceived swelling" is part of normal chicken growth?? Any advice? THANK YOU!!
