Hello!! New! I have 4 hens (2 roosters are being returned with 3 more pullets planned soon). Some of my lovely ladies (1 Barred rock, 1 black astralrop, 2 lights brahamas) have started to lay!! But, I built beautiful boxes placed them 12 inches above the ground with a roost. And they lay next to the water or out in the pen. Should i put the nesting boxes on the ground?
