We have a group of 10 mixed breed girls that seem to have gone on strike. The oldest are about 2 1/2 years old, and until about 4 to 6 weeks ago we would grt 5-7 eggs daily. A dog attacked them, didn't kill any, but sure shook them up. Since then 1 maybe 2 is as good as it gets. They are free range in a fenced area about 25 x 80 ft. Any ideas? We had to BUY eggs today... I could hardly open my wallet!
