I brought home three 5-month old Welsummer pullets yesterday, and have them in a separate run, away from my flock. All three looked great to me, when I picked them up (clean feet, clean feathers, clear eyes, good weight and overall appearance), but when I got them home and looked at them in the sunlight, I noticed that one of them had a clear liquid oozing from one eye. I cleaned her eye with Colloidal Silver, and she looked fine the rest of the day, but today she ones again had clear stuff running from her eye, and when it dries, it turns into sticky balls which are really hard to remove from her face. There is no swelling or redness anywhere, and she seems to be in good condition otherwise. She did have some smelly, yellowish, runny poop yesterday, but nothing too out of the ordinary looking. Her 2 sisters are fine. Could this be something I need to worry about?
