What would be a good sized grow out pen and coop/house for about 70 chicks, I`m fortunate enough to have help this weekend to build something. BTW, the chicks are all standards no bantams.
Orpingtons,leghorns and andalusians. thanks Tony
grow out pens for chicks.i built 3 4ftw by 6ftl by 2fth brooder pens on legs 2ftt.an each pen will hold 25 chicks from babies till 5 or 6wks old.now for your henhouse id build like a 25 by 25 henhouse.an would make a 25 by 100 henyard.
If the chickens can spend most of their time outdoors, 4 sq ft per bird (once they reach adult size) would be like a 10x25 ish house; plus a run of 6-10 sq ft per bird (at adult size) would be from 10x40 or equivalent up to 20x35 or equivalent.
If they won't be able to spend most of their time outside in a dry pen, you will prolly want to make the house (coop) larger unless you wish to court factory-farm conditions including pecking and cannibalism and so forth.
(edited to add: it depends how long you'll be leaving them in there, of course... if they'll be going elsewhere when they are 3/4 grown you could probably go with somewhat more birds in somewhat less space)
