No I don't. Years ago, there was an established poster, who treated them more like livestock, which I am comfortable with. She said, that if they are active, bright eyed, eating and laying they are fine. I go with that.Do you ever check them for medical issues? I just like to look at them once or twice a week to make sure nothing is going on.
Mine have plenty of room. I do not expect them to live forever, and I like multi-generational flocks. As far as I know, I have never had a medical issue. I don't read the medical page on here, because I secretly believe that a lot of people like to doctor their birds just to be doctoring.
I do watch them, we are ranchers, so watching animals is what we do.
