You are blessed to have that luxury, so many of us are still working and schedules are packed with kids, work, education... no end to the demands on time.
In my opinion, not having the feed available 24/7 puts you at the mercy of the chickens, you aren't raising them, they are raising you. And the OP in this thread was super well intentioned but had no idea she was starving her flock and blamed the bad behavior on the chickens. Keeping the feed in front of the hens 24/7 eliminates so much trouble. But that is just my opinion.
