my chickies are 4 months old. they are buff orps. I have no idea about nest box training? also, what about the light issue. Right now it's getting cold so I switched the blue 85 watt light to a warmer red light. is that all right? the chicken free range on the weekends and after work (only about 1 hour of light left before they leg it with desperate speed back to the hen house!) Will they lay with the warm light or does one use natural - which I have noticed causes increase in their aggressive tendencies as evidenced by more posturing and pecking! that's not good! Also, I've noticed that adding cracked corn to the grain creates yellow poos. What other grains are good to add? Horse oats? Wheat? Remembering that nasty habit of feeding poultry the dead remains of their friends and relations - remember that ineatable chicken remains were processed back into chicken feed. Is that still done? So do people feed feedstore chicken feed like blue seal or nutrena?? Is that even true anymore?
