A couple days ago I went to check up on my chickens and noticed that one of my chickens had a swollen eye! It looked really disturbing so I was not able to look at her for very long before I ran inside like a little baby! But I decided I was going to treat this so I got warm water and epsom salt to go put on her eye. After I did that I noticed that another one of my younger chickens had bubbles in her eye!!! I did the same to her eyes and left it as it is. The next day I came out to check to see if they were doing ok but another chicken got it!!! This was on one of my oldest chickens! Her eye was swollen shut! I got warm water and epsom and put on all of my chickens eyes. The next day my older chicken whose eye was swollen shut did not leave the roost at all for the entire day! She even laid her egg from the roost! Both of her eyes were swollen shut! I kept on putting warm water and epsom salt on all of my chickens two times a day for three days intel I finally saw improvement! My older chickens eyes are doing a lot better now! But she is still very weak and rarely comes out to free range. And sadly I noticed that one of my Buff Orpingtons just got it to! This is so frustrating! By now I know that all of my chickens have been exposed to this mysteries infection or something by now. What do I do!!??? And what is this!!?? Please anyone give me some advise! I really dont want to lose any of my chickens! I will get some pictures for you guys if you want them.
