I am looking into expanding my current flock of 6 red sex links to 24!! I am in the process of designing a new coop which I am building from scratch. I am in construction so I have a lot of materials handy. I have had my current 6 for about 2 years now and have learned a lot from my original coop design. To me, it seems like I really need to increase the size of the coop, looking at 8x16 with a 6' wall height and 8' peak height. I am great with proper air flow, plenty of perch space (higher than nesting boxes), using TPO roofing membrane for my floor (amazing for clean up any time of year), windows, door for them and myself. The things I am wondering are 1) I go through about 50lbs of feed a month right now with my 6, I have a 3" pvc pipe feeder that lasts about 3 days. Does anyone have easy fill ideas for the upgraded amount? I am leaning towards a gravity fed metal can concept suspended from the roof. 2) Similar question for the water. I live in upstate NY where it gets cold. running electric isn't an option. Right now I change the water twice a day when it freezes, though again 24 birds drink more than 6. 3) any other details I may need to know when increasing the size of the flock so much? any info or questions would be a great help. Thank you.
