My chickens i have about 14 chickens who should be laying, and im getting one egg a day, and a bunch of the younger girls have discharge from their noses and some from their eyes, i think it is either MG or cocci but other than the things i have noted above they dont seem to be sick, one young girl however i think is going blind, when she was a bit younger her eyes used to get all yucky and scab up, they dont anymore but now they look clouded and i think she may be going blind.
