Hi I'm WendyGrama, new to the forum's but only a little new and out of touch with the chicken thing. I am currently housing 11 mixed standards and banty's from Welsumer & Wyandotte to the wee Seabright couple. There should be two roosters a Welsumer and the Seabright, so far so true, but we are only into the 2nd week. Soooo they started in a very large cardboard lined rabbit cage, that lasted the 1st week... they are so active it was a shame to see them limited and the water'rs were constantly needing to be cleaned out and the mash spread everywhere but in the feeder...
Now they are on my studio floor using old paint sheets for footing and bedding for now, seems easiest to change out daily, wash and replace, they have 5 times the space, several rocks helping to anchor the sheet bedding and cardboard walls and a long piece of desert wood I dragged in the other day. All of them are climbing the rocks, pecking at them, jumping off, stretching their wings, wandering independently and then gathering together as a flock at night mostly, during the day they spread out all over.
So now I am building a smallish coop but with a good size pen 16' by 12' and 6' T. The coop itself will only be 3' by 8' but I am roofing over much of the pen and extending the sides as part of the pen too, unless the weather is really bitter they will have constant indoor/outdoor, nesting boxes will be built outfrom the coop and feeders and water's kept in open space in the pen. 
If a hen is broody I will likely remove her or cage her in the coop so she is not picked on. If the roosters don't get along... well I will deal with that if it happens.  The thought being I will seperate the banty's from the standards.
In the past I have housed ducks, all sizes of chickens and multiple roo's all raised together, not to mention the goat who used to occasionally join in too. They mostly free ranged.
Because I am now in a 1/2 acre lot neighborhood with lotsa dawgs, cats, skunks and the odd coyote, these newbies won't get that option unless I am home, but the pen is right beside where plans for the veggie beds are so they will have seasonal option there with partial fencing and out back under the mesquites about 80' by 20' I have recently seeded with native grasses, wildflowers and yellow clover for possible rescue home for burrow or goats... will also be an option partially fenced with maybe a portable coop for there.  And there is the back lawn/weed/planned fruit tree yard, but only when I know exactly where Ruby Kitty and the Dawgs are!
Does all this sound reasonable or just too much info. Its been so long since I have had chickens and I am really enjoying the chicken pyschology through observation. Will set up pix another time, way too overwhelmed at the moment!
