Unless you find evidence of egg eating, I'd more likely assume they are not laying.Well we object because we want the eggs to eat and sell! We have 12 chickens. 6 white leghorns we hatched last summer. And 6 other breeds we got from feed store this past spring, only 1 of whom is laying so far. One or more of them are who we believe are eating eggs. No wet spots, no shells, nothing. They have a bulk feeder with four spouts. The coop is 4'x8' plus attached covered and enclosed run of 8'x12' I think.
Are your nests secure enough that eggs cannot easily be rolled out?Some are not laying. But I've seen eggs disappear too. Seem them in the nest box, then come back to get them when done with other chores to take inside and gone!
