Ideas on breeding pens?

[stickers]

Planning to build new pens in spring and dividing breeds into their own pens so my horses can have their barn back. Will be starting from scratch and would greatly appreciate ideas/pics. I will be needing minimum of 7 individual pens lean to style each holding up to 12 large fowl.

I would say for that many large fowl I would make your pens 10x10 at the largest or 8x 12....smallest I would go would be 8x8. With that many pens and that size you are looking at a building that would probably be about 10x70 or 8x84. If you are going to add runs to them then that would of course add alot of square footage and your pen size could be smaller.
I have built similar buildings in the past, albeit smaller because I was raising bantams and the pens did not need to be as big as yours.
Hope this helps some,
John
