Ok, I know the repeated yawn type behavior is a sign of gapes. And I do believe my chickens had that in the past, and I was able to treat it. But what I am asking is....like when my one chicken wakes up after an afternoon nap, she will yawn, just once....a big ol yawn, and then go about her business? So...do they ever really yawn for real, or is it always a sign of a gape problem? Or do I need to treat again, ya think?
