Help - i've finished framing an 8x10' chicken coop using 2x4 vertical boards to create each of the four walls with rafters on top of a 3/4" plywood base resting on 4x4 posts. My problem is, the frame seems to be very wobbly. it doesn't move in the wind but it does wobble back and forth when pushed on it. Is this something that will go away when I put the siding on it or do I need to do something else to reinforce the frame before I proceed. The plans I used, aside from some incorrect dimensions, doesn't mention anything about reinforcing the coop. The last thing i want is to have it collapse and kill any my chickens. Any advice?
