Our cat chased a hen pheasant off its nest just under 3 weeks ago and found 20 pheasant eggs and 2 duck eggs in it. Thinking it probably wouldn't return i took 9 pheasant eggs and the 2 duck eggs out and put them in the incubator. I candled the duck eggs and found one wasn't growing so threw it out.
