I have 4 juvenile peacocks and plan on getting more. They are in a really neat temporary pen. I wanted to know if anyone had some suggestions about materials, shape, size of pens for someone with a budget? Should I build with an eye towards them becoming adults? Also the chickens took over my adult breeding pen but from the looks of the breeding pens I have seen on here so far ours wrong. My husband can build anything. I don't know if his ideas on this are gonna be? Um the right way to go. I would like ya'lls opinion, please. Housewife/Homeschool Mom, 2 India Blues, 1 Black Sh. India, 2 juvenile India's , 2 juvenile White's, 16 Golden Laced Cochin Bantams, 7 Easter egg chickens, 2 dogs.
