One of my Road Island Red chick has clear like saliva coming out of her mouth each time I pick her up. It's clear, a little bubbly & stringy. Can anyone tell me what this means? She is the only one I had to soak her botyom to get dried poop off which had bern blocking her. She seems to be pooping fine & shiws no other signs that I can detect so far. Last time I saw this is when one of my hens died to smoke inhalation.
