It is a 45-Gallon plastic tote that I plan on turning into a brooder for my soon to be had pets. We went and priced hardware cloth at the Lowe's near our house (a block & a half down the street) and found a 2' by 25' roll for about $30. From the roll, I plan on making a "vent" on half of the lid for ventilation and a light (brooder fixture is $8.99 at the local feed store and the bulb is $6.99). The green handles fold up from the base to "lock" the lid in place, a nice feature since the brooder will share the space that we currently use for our cats' food and potty box. Also, one side has wheels on the bottom so it will be easy to move around by myself. None of this besides the size of the tote is useful in deciding how much space is there, but thought I'd add it so someone doesn't think I'm leaving it "as-is" for the chicks. The plan as of right now is to be at the feed store on Feb. 1st when they start taking orders for the chicks they will start getting in mid-March (I was hoping they would have them in-store mid-Feb so I could go get them while my nephew is here to enjoy the experience). I know I want 3 (max. # I can have in the city...), along with the "types" I want for the most part (EE, though the feed store says they're Araucana's, for sure...maybe a RIR, and either a BO, BR, SLW, or a sex-link, they have both Golden & Black). So, how long can 3 chicks spend in my "extra large for a small flock" brooder? My hope is that they can stay in this until they are big enough to go out to the coop (which is currently a shed awaiting remodel once the snow subsides). After they are big enough to go outside, more remodelling on the shed/coop will take place. We don't yet have a "set in stone" plan for the run, mostly because I was the only one planning all of this until we had a talk today about supporting our partner in stuff they want to do instead of standing in the way ( ). A 50' roll of 2"x4" welded wire fencing is $45 here, and hopefully enough to make a decent sized run for 3 hens (they'll also install it for an additional $5 (I'm guessing per foot), 5'x10' run, plenty big enough, lol. The pop door will go in before the run does, but I will lock it up tight until the run is built. Until then, I have a dog training pen (8-10 2' panels all attached together) that I plan to use while I'm out in the yard with the gals. All of the future accomodations for our 3 hens seem oversized for the number, but I just can't afford the $1600 coop at the feed store right now, so they will have to use what I already have here, an underused shed that is roughly 6' by 10'!
