I have 6 hens (2 barred rock, 2 prod red, 2 leghorns) the BR hens were laying when I purchased! The other four were nogt! I got them home and the barred rock layed for about a week... All the sudden they stopped. I thought there was a snake or varmit getting the eggs so I placed a egg in the nest and it has not moved. The have 24/7 access to feed and fresh water (Laying pellets, scratch, oyster shell) they also have free range in daylight hours!
