We had a hawk attack a while back which unfortunately resulted in the death of our hamburgh rooster and one hen. The remaining hamburgh hen has lived in the "isolation chamber" ever since, as she had been injured. She has made a full recovery and is as healthy as ever (except having suffered the loss of eyesight in one eye) but has not laid an egg since. That's a good four months ago. Should I continue to wait? Or count her out? Also, we have a pair of brahmas that have not laid a single egg in the four months we've had them. Thoughts? They get the same feed and freedom as the rest of the flock. Should I start weeding out the non-layers completely or just leave them be to see what happens? If I switch the non-layers to meatbuilder from layer, would they be good to eat?
