I've got five pullets who are somewhere around four months old. Yesterday I noticed that two of them have runny eyes; the girls in question are a Buff Orpington and a pullet who's either a production red or a RIR. Today I snagged some photos. The five of them sleep altogether in a coop, separated from my other chickens. The bedding I use is straw, and they eat an organic lay crumble. It's been really windy lately and the area we live in kicks up a lot of dust. Is it possible they've just got some dirt in their eyes and are having a reaction from that, or do you think it's something more sinister? I've only been working with chickens for under a year, and I've not seen this before. Any opinions, thoughts, or past experiences would be much appreciated.
