I will be keeping up to 20 breeds at a time this winter but only 3 or so of each. The idea is that we will be breeding very small quantities of several high end birds. I would like ideally one building, but am willing to accept 2 if I have to. It is temporary as we are moving next year to a farm where I can build larger. Ideally it will be something that can be repurposed as a greenhouse Here's the list of must haves Repurposable as a green house holds 20 breeds + must withstand massive snow loads must withstand average -30C (-22F) winters I am thinkinking something like this. I think this is one of the other members, I found it online . If I did this as a 12 x 30, I could divide it into 5 pens each side measuring 4.5' x 6 with a 3' walkway. The cheapest we can do it $851 per building. Price is harsh but okay. If anyone else has ideas or pictures I would SUPER appreciate it!
