We use a mobile coop with a "Premier One" Fence system. We also clip on of the wing on each bird so they cannot fly away. Our fenced in area is 80' X 80' and we move the flock weekly behind our cattle to help with fly control and to get them into new bugs. Having them on pasture reduces the amount of feed we need to give and makes for healthier birds. I am assuming you have hawks like we do and they can be a problem. To curb that we try to attract crows to live in our woods, hawks and crows don't get along, the crows keep the hawks out. We had a guy bring an electronic caller over and they have not left, not sure of any other way to attract them, but we are sure happy to have them.
Get your self a big rooster and one that is semi aggressive, he will keep the hens from picking on each other and he will protect them from predators. ( I have a short post coming out soon on a hawk attack and how it turned out). The last thing I would say is don't put you hens out to pasture until they are 14 to 16 weeks old. Before that they are just to small and are easy prey for all sorts of animals. Good Luck! Let us know if we can be of any more help....
Thank you so much! We will definitely be using this info. It's been ridiculously hard to find out what to do with them! We have quite a few crows around our property already, not sure why, but I didn't know that crows and hawks don't get along! I will tell my siblings about this, and hopefully we can put it into practice!
