I have my hens in a green house with open rafters. my egg count went from about 10-12 eggs a day from 12 hens to 2 every other day. Now I know it is getting to be winter but that was too drastic all at once. So I began investigating. Even though they have 3 nest boxes( in which I have only found 3 eggs in the entire time) they prefer an old plastic wheel burrough. It has sides abour 18 inches high all around and a plastic bottom. I forgot it in there one day and that was where they picked to lay. So I figured if they like it i lovr it. Left it in there and went on with life. So upon me getting currious and tearing my green house apart. One of the hens flew up into the rafters. So I look up and the light bulb goes off. SO I get the lader and get up there and all of a sudden I find 25 eggs in a corner of the rafters. Great that I found them, but now comes the issue of how to get them to stop using the rafters. and go back to either the nest boxes or the wheel barrough again. Any suggestions? I am trying to avoid closing the rafters off because from time to time I use them for storage myself.
