I have considered raising chickens for many years now but only recently came up with an idea for a coop that I like. I'm sure that you are familiar with the yard design where you have a fenced in run with a structure similar to a dog house that provides shelter. This is the design that I am employing using a 5' x 5' x 10' run created from pvc pipe and poultry netting. For the actual coop I have a 50 gallon sterilite tote that I purchased from Walmart. It is turned upside down so that the lid becomes a litter pan. This container provides almost 8 square feet of enclosure. I have installed a large crawlspace vent on one side and a wooden door that drops down to act as a ramp on the other side. This arrangement would comfortably hold 5 large birds. Kinda like a poor mans eglu. I have constructed 2 coops using the sterilite totes (I call them chicken castles because the totes are grey and they have a draw bridge type ramp). My question is this. If I have two of these castles together in the same run can I get the birds to use both of them or would they all try to pack into one? I know that when you first put the birds out you are supposed to pen them up for a period of time in the place that you want them to call home and they will naturally return there. Does it just follow that if I had six birds I would pen up three in each coop and then they would naturally split up and return to their respective homes at night?
