Raising two keets for the neighbor and figured I'd move them out in the chicken coop/yard when they got to be as big as the young banties out there, but don't know if I can. banties are 9 weeks and keets are one week. by the time the keets get to be at least close to the chicks' size approx. how old will they be? and am I right in figuring that when they are fully feathered they no longer need a heat lamp? though this far into the summer I'm thinking they wouldn't anyway, heck I could put them out there now if they weren't so small. it's hitting the century mark during the day.
