In recent years I have been running my layer flock in the same fencing with our broiler chicken tractors. This presents certain problems but solves some others. In short, the layers always seem to find a way to get where they don’t belong but the layers clean up the feed the broilers leave behind. They also knock down the forage ahead of the tractors as they hunt for insects. That kind of helps when moving the tractors but it slightly soils the clean sheets we give the broilers each day.
Anyway, we have run this way for several years and I always swear I won’t do it anymore. But it’s kind of nice to only have one set of fence to move.
