OK, i have one pullet that i found today with the bubbles in the eye, and looks like there was some nasal discharge, but has dried up. she has no odor and is eating and drinking just fine. is it not possible for chickens to get a common cold or allergies this time of year? i am even having sinus problems due to the weather. i have quarrentined her with antibiotics, but if this is something simple, i don't want to cull her needlessly.
