Hello again everyone, I have a few more questions but this time it is about the comfort of my new feather friends. I just bought all of the materials for my coop but before I begin building I want to double check that the size is alright and confirm a few things. #1 I went, roughly, with the 4sf by 10sf rule that I have seen since joining here. I will be getting 24 silver laced wyandottes and am building a coop that is 12x6 with two sets of externally attached nesting boxes on either side that will be 12 inch deep by 8 foot split into three. Including nesting boxes there will be approximately 88 square feet of room which is just slightly under 4 square foot per bird. It wil be 4 foot tall and and additional 3 feet off the ground. The whole back will open to easily clean out the feces and detritus. This has been the most comfortable method I have come up with for my rabbit hutches over the years. The attached run will be 144 sf which is 12x12 but there will be an additional 12x6 under the coop which is 72sf. Combined that is a total of 9sf per bird in the run. Everything said, I will not hit the 4/10 rule but I will come rather close. Does this sound okay or should I be shooting for more? # 2 where does the 4/10 rule come from? If you search the net that is not the suggested number everywhere. It is common but so is 2 square foot per bird in the coop with a total of 10 square foot including the run and the coop. I have even seen people suggest the smaller coops in colder climates. In the end, I didn't want my head to explode so I came up with numbers that worked for me and they came close to what seems to be the suggested minimum requirements here. I know some people go with much much more space and if needed I can go that way in the future but for now I just have a little bit of wiggle room. Thank you for any suggestions you might have.
