we're newbies. One of our Welsummer hens is keeping her eyes closed for most of the day (seems mostly in the afternoons).. she's eating ok, drinking ok, crop seems ok (not full or empty, not mushy either)... we'll feed the chickens some tomatoes... she's right there, acting fairly active and gobbling up her share. Then a few minutes later... she's off by herself, with eyes close... hunkered down by herself. We were told she maybe ready to start laying, just not sure that's it. She's free ranged during the day, currently on starter crumbles, always has grit, just started oyster shell this week for all of them. Today is day 2 of the issue... and now I do hear a little bit of breathing issues. A little bit of heaving breathing. not panting or anything but, i hear her bring a few heavier breaths. ... (we did just get past a major 100 degree heatwave) Any assistance appreciated!
