Constantia had two hens and a cockerel. She was getting just the one egg a day. One hen was laying daily, and the other wasn’t. Constantia wasn’t sure which hen was laying and which one wasn’t. They were both white and looked the same.
Constantia would have liked to have used the eggs to hatch out more chickens. She didn’t do it though.
“I don’t want to set eggs under a broody hen only for her to hatch out chickens from the non-egg-layer. I don’t want to propagate non-egg-laying genes,” said Constantia wisely.
