First it was a hawk every 3 days taking 1 or 2 depending on size. I fixed that problem with a net covering. Then something took 5 in 2 days, so I rebuild the whole run with fencing on the ground altogether with zipties,wire,and staples. I chicken wired the windows. There didn't appear to be any holes :-\\ until I looked up at the gable vent area. Then I was like no way. So ill cover those and see what happens. At this rate ill never have eggs :'(
