I bought a dozen chicks last spring. The sign on them at the store said all hens so I didn't even bother to check. One turned out to be a rooster. Before the end of the year all the hens had been taken by predators and the rooster was the only one left. Not a scratch on him. I used chickens for bug and rodent control as we've renovated an abandoned crack house that had been almost reclaimed by the forest. We gutted it to the studs, it's basically a brand new house, but the contents of the original house had been strewn throughout the property. Water heaters, refrigerators, junk cars, broken furniture, the contents of a kitchen, about 40 old bald tires. I swore they must have brought more junk to the site. Finally a neighbor told us the previous owners had bulldozed a fully furnished burned out mobile home in the backyard about 20 years ago. That junk fest prevented us from running a lawn mower for a whole year! We considered goats but were afraid goats would die from eating broken televisions, silverware, beer cans, carpets, and broken glass. All hidden under 7 foot tall weeds. We chose chickens to clear away the weeds and snakes so we could get to the debris. Well, long story short, we've cleaned up the trash enough to go barefoot, but we've actually given up free ranging hens. Now we've only got roosters. They've moved on from cleaning the yard to cleaning up pasture. Fenced because they are MEAN! Pity the little hawk that tries to mess with one of these monsters. We can only free range hens with a net over their heads.
