After having built my first coop, ( http://picasaweb.google.com/pyxicephalus/November272009?authkey=Gv1sRgCPWv75CCq_PorQE# ) I thought I'd share my opinions and observations with new chicken keepers like myself.
I observed the 3-4 sq' rule per chicken and this worked fine for my six hens, but I decided to add two more hens for a total of eight hens, still my coop is large enough but...
The two new hens are older, by several months and even though all get along fairly well, things inside the coop have changed with the addition of the new birds. The older birds are as you would guess at the top of the pecking order so inside the coop, there's a little more jockying for position than before the addition. I've had to break up a few fights, nothing severe but definitely not to my liking.
The tension inside the coop is more relevant these last few days as we have had rain, rain and more rain!
So long story short about space IMO is to build larger than you think you need. My chickens free range every day but if the weather is really inclimate they may be cooped up longer than you want them too & this is where things can get out of hand.
Another thing to consider, based on my limited experience is ease of perch access. At the end of the day, all chickens are in and most all are on the perch, but I have one hen that's a little timid, perhaps she's a little slow in the head too (From what I've observed) she just has trouble figuring things out and I find myself helping her up to the perch quite a few evenings. She would get there on her own eventually, but if my coop was deeper, she most likely would be better apt at getting up to the perch.
Now mind you, this particular chicken is at the bottom of the pecking order, so she is looking up, trying to get up on that perch, with seven other hens staring her down. I really believe with more space in the coop these problems would be resolved.
For the most part I am very pleased with my coop but will be deepening the coop and extending the roof on both ends as well, all as soon as this rain stops, if it ever does!
All feedback is of course welcome and expected as I've come to find this forum is chock full of many, many members with all sorts of experience and opinions.
Hope this post helps someone.
