Hi everyone-- I'm new here, and relatively new to owning chickens. We've had our little flock (4-6 hens, depending) for about two years now. In that time, we had one hen become eggbound---we worked with her, massaging her and keeping her warm as needed, and she recovered each time (and then somehow the coop door was left open...but that's another story). This week, two of our hens became eggbound, first time for each. Both died. We love our hens and are devastated. I'm wondering what we are doing wrong and if we are overfeeding, but I can't find any guidelines for how much to feed or how to tell if a hen is overweight (it's not like I can get a waist to hip ratio, or feel for their ribs). Any input would be very much appreciated--thanks in advance!
