I had two hens hatch out babies starting at the end of May. Since then the entire flock has been on starter feed. In the last three days, I have had zero (0) eggs. Is this because of the starter feed? Does anyone have any advice? I have put out oyster shell for the adult chickens but I have no guarantee how much they actually eat. Should I put that in a feeder? I ask because right now it’s just in a livestock feeding tray. I am very worried. Any advice or information would be appreciated.
