Ok so here is the coop and run... The front of the coop has an aluminum plate with 1/4" circles drilled every 1/4"... Below the plate is the entrance to the coop. Unfortunately when the door is open the vent plate is mostly covered up. At the moment this coop is 4' high, 5'wide, and 4' deep. I plan on adding an aditional 4'deep x 5'wide x 6'tall space, enlarging the coop from 20sq feet to 40 sq feet... My biggest reasons for wanting this add on is roost space, and ventilation. When I add onto this coop the front will be completely removed, and the two halves will be framed together. Would you all recomend that I wait until I build the addition to this coop before putting any holes for ventilation? Or should I go ahead and add some to the top corners on both main walls, and just seal them when its complete? So Ive been creating my suply list, and my lumber list is getting pretty big! lol Does anyone use Cedar lumber in their coops? I live directly across from a cedar mill, and have access to all the rough cut lumber I could want... I know cedar shavings and chicps are a HUGE no no for bedding. Because of the surface area on the pieces combined with the toxic oils in cedar... But what about lumber? Much less surface area, and I would emagine the fumes wouldn't build as much because the lumber doesn't get stirred up like shavings do when used as bedding... PLUS there is ventilation to keep air flowing through the coop, wich would keep any fumes to a minimum... So Is it worth building out of cedar, when the matirials are free? Is it even safe? Or am I talking myself into something thats not such a good idea... I'm also getting ready to build a second coop to house 6 Ameraucanas and 2 Marans... Would a 6' wide x 8' long x 6' tall coop work for 8 birds? And again... Free cedar lumber, or do I purchase typical lumber??? If it helps... The cedar that this mill, has is all locally grown. Non aromatic, just standard PNW cedar.
