Right now, with 3 different aged sets of chickens in 4 different coops (well, one of those is a duck house the ducks never took to using so a couple of the pullets WANT to use it like a great big nest box), I'm kinda stuck with opening up 3 of them. The Big Coop with most of the chickens has an automatic door. The rooster and those hens are outside waiting for me when I go out to open up the other 3 "coops."
I usually go out around 6:30 a.m. on weekdays, maybe 7 or a tad bit later on weekends.
Big Coop, rooster and 6 pullets, auto door.
Medium coop with attached pen (but inside the entire "complex" and its run), with four 16 wk old pullets.
A-Frame coop with bottom section enclosed area, with one hen keeping a broody hen company at night.
Duck House with four 9.5 wk old chicks.
The ducks sometimes sleep in the Big Coop, usually they just snuggle together somewhere on the ground in the run. I WISH they would go into one of the coops or the "inner" pens of the two coops with that extra security area.
The main Coop is the one with the automatic door; I don't mind dealing with the 3 other "coop" doors because those are "special" needs structures. Integration/segregation for birds to join the flock, a broody hen, that sort of situation which I think requires extra attention on my part.
