OK—so, the title of this post is really a trick question. If your laying hen is crowing, then she’s already undergone a hormonal change that is causing her to display rooster-like qualities. And since roosters don’t lay eggs … guess what? Neither will your crowing hen.
I only know this because a few days ago, I was in my goat barn, milking one of my goats, when I heard this poor, strangled little rooster crow coming from just outside the barn. I set down my milk pail and headed toward the sound, expecting to find one of the neighbor’s young roosters in my yard.
Instead, there stood my fattest Buff Orpington hen with her head cocked back, crowing like a rooster.
Yes, this is a true story. And I have a video to prove it.
