We have 9 "laying hens" all around 1 1/2 - 2 years old and 3-4 new laying hens (around 6 months old), we find from 2-5 eggs per day in the coop. I look around their yard & have only found one, one time. Do you think they're laying them out in the yard & the others are eating them? Should I be getting more? The 9 layers are: 2 Silver Laced Wyandottes, 5 (what appear to be) Blue Orphington/Araucana mixes, & 2 Barred ?? mixes. The younger hens are: 1 Partridge Cochin, 1 Black Cochin, 1 Buff Orphinton & 1 White Rock. Thanks!
