I have a pair of rollers I am trying to figure out why the won't lay eggs... they have been paired for over a month, have a nest box they have claimed, but they still haven't laid eggs. Is it possible they are both cocks? The one I think is the hen did initially seem a bit "cocky" - but when I put her in a pairing box with a known hen they displayed no breeding behavior, and shortly after I took "her" out she paired with the cock she is with now. They are definitely paired, though come to think of it I haven't seen them mating much - but that could just be that they are and I'm not there all the time. They are healthy, and though they are from a late batch last fall, another hen the same age is on eggs, so the hen should be old enough. Any ideas? Otherwise I might try breaking them up because I have an unpaired roller hen and cock I could put each with and see if they snap into breeding mode then.
