It's the three runners. I tried to focus on the one. The others look the same. ONLY the runners are affected. It just happened yesterday, but I'm not sure if it's an actual problem or not. It looks 'wet' but it hasn't gone away from the past two days. They are 2 weeks and 4 days old.
I tried doing other research but couldn't really find anything. Hopefully someone here has some experience, it would be greatly appreciated. They have clean water that they can put there bill in. But I haven't seen them go as far as the eyes (it is possible they can do it, but I haven't witnessed it)
