We have 7 laying hens, an older(6yrs) black australorp-the last of the older flock, and 6 white leghorns(3yrs old). We have gotten no eggs, other than an odd 1 or possibly 2 every few days/week. Are they done already? I find it hard to believe that the australorp layed well into her 5th year and the leghorns would be done before they even hit their 4th summer. We thought perhaps it was the layer mash we were getting from our local feed store, we have begun changing it out....but maybe not?
