In the last two weeks I lost 3 red golden hens to a great horned owl! Too bad it took me so long to figure out what was getting them and how! To try to make this short, I had a perch about 18 inches down from the netting on the top of my pen. The owl would land on the netting, the netting would sag, then it would grab the pheasant by the head. In two of the cases it managed just to pull their heads off, but the last one it held on good enough that it was able to eat the breast before it dropped it in the pen. I knew a cat couldn't of held on that good and I also then found a horned owl feather on the ground. So I have since lowered the perch enough that they can't reach the pheasants and I haven't had any problems since! The problem I do have might be worse than the owl attacks! I'm down to 2 males and 2 females. Yesterday I noticed the one male's eye was watery. Today the one eye is completely shut and the other eye looks to have a slight film on it and I think its sight is almost completely gone. Does anyone know what this might be? I put an antibiotic in the water today but I dont think he can find the water anymore. I'm just hoping this isn't something that wont spread to the remaining three healthy ones!
