I have 1 Easter egger 2 Cochins 1Australorp 1 Barred rock and 1 Buff Orpington. So a total of 6 chicks I'm starting to plan a coop build along with a run. Just wanted some advice on coop size and run size. It will be within an 40x40 4ft chain link fenced area as well which I will let them out to forage but want the option to pin them up because not sure if they will fly over 4 ft fence into neighbors yard. Don't want complaints.
