It may have, but the amount of space your birds have is way too small for how many birds you have. The BARE minimum recommended amount of coop space per average sized bird is 4sq. Ft and for a run is 10 sq ft. If you were to combine your coop/run and consider it all coop in your calculations it would be 60sq ft. 60/17=3.5 sq ft per bird and if you consider your new addition which would be 80 sq ft the equivalent of a run 80/17= 4.7.... 3.5 sq ft of coop per bird and 4.7 sq ft per bird for a run is even under the absolute bare minimum recommendations for space. Not to mention pekins are almost double the size of average size duck breeds and require the extra space. This little of space will only lead to health problems, bullying and possible cannibalism.So my coop is about 6x10 (coop including the run) and then we put an 8x10 addition which is basically an open pen. I do keep them in the coop/pen. I haven’t let them free range yet as we have had a red tailed hawk nesting right above the coop for the past two years. I keep a kiddie pool that I fill daily for the ducks. And I make sure they get in there at least once a day to clean up. I am not sure where the eye thing came from with Pickles (my Pekin). Her legs didn’t develop quite right so she doesn’t move as fast as the other two ducks and she is definitely at a disadvantage when it comes to defending herself. I wonder if the infection just gave them a reason to pick on her?
For the eyes, Terramycin is awesome for treating eye irritations and infections. For her legs what you are describing is a niacin deficiency which is very common in pekins due to their large size and fast growth rates causing them to require more niacin then most duck breeds. I would highly recommend you purchase Durvet's B complex and administer orally via syringe or injected.
