20 of my own eggs. 4 RIR, 16 BR/RIR cross, and 4 mystery eggs from a friend that I am not sure are fertile or not. My last hatch was a big ZERO. I had trouble with temp spikes, so I reconfigured my homemade incubation system to be hopefully steadier temp wise and am trying it again. Countdown to 8-30, assuming I counted correctly!
