Not sure if this is a flock management question or an egg laying question because the issue involves both. We have two 1.5 year old hens in a large enclosure. We recently added two 4 month old pullets to the enclosure. When the pullets were first added to the flock, the older hens were very hostile and alarmed, and this marked a sudden stop to egg laying. Three weeks later, egg laying has not resumed, even though the pecking order has been sorted and relations seemed to have improved (though they still walk around in pairs, never really mixing). About 5 days ago I added some eggs to the coop to see if I could encourage laying to start again, but so far we've had no results. Any suggestions as to how to encourage the hens to start laying again? Thanks!
