It is currently housing 17 chicks.I built this recently and had it ready to be occupied for my chicks that arrived the day after fathers day. In the pics I didn't have the pop door cut out, but it is now and I built a screen door so that the main door can be open and the screen door gives it more light and ventilation. All in all the coop cost under $400.00 to build. It took me about two weekends to complete (I had a little help from a brother in law and my two children). Sorry if some are blurry-they are from a camera phone. Oh and I did run electicity to it for a light and one outlet (the light can be switched on/off the outlet is constantly on). 13 Red stars 1 dominique, and 3 Auracaunas I will be creating a run for free range- I'm just doing what my dw wishes...to be continued.
