I have 3 laying hens and I actually had to buy eggs this week! I have gotten 2 eggs this week out of 3 hens. All 3 had been broody and I got them to stop and they started laying again for a few weeks, and now they have stopped again. What is wrong? Is this normal? They all seem perfectly healthy. Is there anything I can do to get them to start again? Thanks in advance for any suggestions.
