I read the post wrong about the measurements on the new coop being built. I apologize. I have been skimming way to much trying to keep up. No excuse. I should not give advise if I cant take the time to read. Your coop if fine for 9 birds. I fed just at night for a month. I just started not feeding at all when the kale, clovers and spinach came up. The ground is thawing and they are moving branches and the wood pile to look for worms and bugs. I have dang mice in my coop so I know they are getting enough food. If they are hungry they eat them buggers. I hate mice..they bring in mites and all kinds of stuff. I am a bit mad at the chickens and ducks for not controlling them better and me for over feeding for too long.
