RentACoop Roll-Out Reversible 3 Compartment Poultry Nesting Box

All I have assembled are the two ends. I stripped a couple of screws because the screws wouldn’t grab the underlying metal and go in. I was trying to install a partition, and again, couldn’t get the screws to grab. It would go nowhere, or the underlying metal would just be pushed away from the screw. A self-tapping type of screw should have been provided. I decided to try and hold the metal pieces tight together. Well, again, the screws wouldn’t grab, and the screw end would just force the receiving metal piece away from it. I tried again, and this time, it grabbed the metal partition, and instead of driving into the piece, it spun the partition. As it did, the corner penetrated the bed of my middle fingernail. The pain and blood is just not freaking necessary! Mind you, I’ve built a mega coop, smaller coops and several metal nest box systems without ever injuring myself like this! Provide your customers with proper screws!!!
