so even since you use them for longer times, you take them off or leave on till something changes? What store could we get them? I'd like to try this before having to trim beaks. Hubby says trim beaks, I'd rather not as you and several others say they change behaviours.@mamatink7 I've used the pinless peepers for almost 2 months w/ my mean leghorns and silver Wyandottes and I tell you they worked great. I almost culled the mean girls on my first year w/ chickens yet I was so torn since they were great layers- enter peepers and they worked. I have 3 generations of hens living together now including the old meanies, luckily I have never had to use it again since they turned nice after the peeps. Not sure if they became nice since they matures and the peepers just bought them time.
