Okay...I was so skeptical to do this but a friend of mine said it worked for his hens. I don't have a rooster and only 2 of my 6 girls were laying...though I knew a couple were close. So I printed out a huge poster of a rooster (which my husband titled "chicken porn") and hung it in the coop. 2 days later I'm happy to report 5/6 chickens laying... WHAT?!? Crazy...coincidence? Anyone else tried this before?
