Well this batch of little ones, will go to the tractor. Not a bad place for sure. They get moved everyday, and the tractor is sized up for the amount of chicks to sustain. Interestingly enough, you have to move it everyday, not because the chicks have devoured everything, but because beyond that amount of chick poop becomes to hot for the land to handle. We have another Auracuana??? that is going on 4 she has free run of the place and I think she thinks she is a dog, lays her eggs in the dog house, naps with them, runs with them, etc...Love the chickies!! Are you going to just let them do their thing, or are you going to try to tame them down?
Lol... just caught the pup (Diesel) messin with the big chicken, had to get schooled. Yes, it is a forced air heating system. The greenhouse being single layer poly is more like a big ass cold frame (with climate controls), sits at about 2000 sq ft, and something like 32K cu ft. So we needed about 300K BTUs to heat the joint. The double barrel stoves are rated at about 70K BTUs per barrel. We have a 12" intake duct that runs from the Greenhouse to a return plenum with a Dayton 470 cfm inside(Actually a 2 speed fan 470/320). From here, the air gets pushed through a 10" duct into the cement board furnace box. On the south stove the return air enters at the front of the top barrel, and exits just above the top barrel horizontally. Out of the box, the shed and into the greenhouse, where the hot air flows through a 10" duct made of poly that we cut 2" holes into approx. every 3'. The duct is suspended about 21" from the ground, just barely blocking the top of the lower vents. The boxes are sealed, and originally the bottom barrel or burn chamber at that time had a 1" ceramic blanket wrapped around it to trap the hot air inside the bottom barrel. Which increased our burn time from 2 hours to 8 hours, oh yeah fuckin awesome... but... our output heat from the furnace was about 80 degrees... WTF>>> The ceramic blanket increased our burn time, but removed half the needed heat per stove for the greenhouse. So, off with the blanket, temps jumped to 120 or so. Then we threw a brick in front of the 2" pipe that is connected to a 74 cfm draft blower, to diffuse the air and woo hoo.... 168 degree output temp. Nice. Burn times are still to be determined since we haven't had both stoves running at the same time, hopefully the t-stats will cycle them off/on, and we'll get our burn times that way. The North stove has a cement board baffle that runs in between the upper and lower barrels. The return air is then forced past the bottom barrel, through a 4" gap, then past the top barrel before leaving to the greenhouse. Output temps were about the same, however, the front of the bottom barrel ran about 200 degrees cooler. whew. Testing with both stoves tomorrow.Heater system is looking real nice. Is it some sort of forced air system? Would love to hook my greenhouse up to my heater. I have a outside wood boiler that I can pump my heating evenly through a concrete floor which would be sweet. Nice looking pup hope he doesn't have a thing for chicken nuggets.
