Love our chickens, just added 5 more. I dote on those little fuckers like pets. I've been teaching the new chicks the in and outs (literally) of the walkway out of the coop. Instead of going down the walkway the little fuckers all just jump on my arms and shoulders and wait to be carried in. spent the morning making the walk way more appealing. Added a step, lowered the angle, etc.
Search deep litter method. Works great, no smell, and great compost.
I made the access door just narrower than the bucket on my tractor. I put the bucket right under the door, rake the litter into the bucket, dump and repeat.
Ran no power, heat or light for the first 2 years, and then we had a pretty shitty winter. I installed a little coop heater, but didn't read the directions. I tossed it on the wall using the mounts. Directions say the chickens basically need to be right up on it. Not sure if it actually made any difference. Coop is 36sqft, about 5' tall inside. They hate the snow, their run is covered but once it fills up, they rarely will come out.
They drink a shit ton more water than you would think, even using nipples. 5+ gallons or more or you're filling it up all the time
