Wish I could post pics, but I can't. Alas. I use a sliding bolt latch, and another swivel latch on the lower edge of the door so it can't be pryed open. Summer is the worst, after all the spring nests have been raided, winter is easier...I can see what's coming...from a long way off.
Hi Achickenwrangler#1 ,
Could you explain swivel latch to me? Thnx! or...possibly post a link to an image of one online?

I wasn't about to even try it again but was convinced that I should try and just do better about making them safe! So I converted my chicken tractor into a fort knox chicken tractor with hardwire cloth, latches with carabiners, pad locks (I am serious) on the nesting box doors because they are closer to the ground so that raccoons can't get in there! LOL I am not finished yet, as I want to add a skirting of barbwire like a mote around my castle. LOL
