I hatch small numbers of chicks throughout the spring and summer. Typically I sell the pullets at 2-3 months, but extra roosters stick around until they are big enough for butchering. The transition pens I used last year worked fine until the raccoons showed up, so I need to figure out something different - I have three ages of chicks living in my tool shed right now! Does anyone have ideas that are super budget friendly and predator proof? We have a plethora of racoons, foxes and raptors. And our summer nights sometimes get down in the 40's, so they need some type of shelter. Last year I had half their pen covered with a tarp, but they got bored and pulled the whole thing apart!
