I owned chickens since I was a kid. Predators were really bad at my old home place so it was a constant battle. Leghorn roosters are mean but my rooster ate catfood out of my hand when I was a kid. They are back floggers and try and sneak up on you. White Leghorn hens are the best layers. Dekalb hybrid hens were equal to leghorns as layers. I knew a family who raised white leghorn roosters to eat. The guy that raised those leghorns sometimes had cuts on his face or ears from one of the back floggers nailing him while he was feeding or watering them. They get much meaner as they age. I heated my coop with a 250 watt light bulb. I took my chickens hot water twice a day in bad weather to give them some heat inside their bodies. I kept a foot of hay on the floor to keep their feet warm and when I cleaned the chicken house it was much easier. I used a self feeder I built. Stored a few hundred pounds of grain for the chickens which made caring for them easier.
