Is that bird wire, or deer wire on your run? The plastic kind? I hate to say it, but if that's all that you have between your birds and predators, with no skirting (that I can see)... Your setting them up for predation. Its a good looking brooder set up, except that you need to secure it much better.
That picture is actually from several weeks ago. It is the plastic kind, but we have since added chicken wire on top, as well as a larger wire skirting over both - just in case. Thank you for letting me know, tho! I appreciate it.
