Have a hen that I thought was broody and when I reached under her to find any eggs her breast was heavy and "squishy". It hangs down even when she walks. She is not broody (sat for about 2 days) and goes outside often. Seems healthy otherwise. I know of another hen in another flock with the same thing. We have had 95-100 degree heat lately--could that have any bearing on this? They are both black copper morans.
