My hen started limping probably 2 weeks ago. I thought she was egg bound so I separated her and soaked her in epsom salt and gave her extra calcium. (She has not laid an egg in this period either), but she seemed better, still with a limp, after about 5 days so I put her back in the coop. She showed no other symptoms until today. Her right eye is closed and she will not open it, and she is still having trouble getting around. Please help. I have read everything and am overwhelmed with all of the diseases chickens can get.
