i have emus, and last year tried to incubate 20 or so eggs but they were all infertial. my hen is laying again this year, but i still havent seen them mate. i see mating behavior, her getting in position, him beside her, both on their knees..etc. but havent seen him "mount her" (sorry if that's crude). because you cant candle emu eggs. was thinking of just incubating an egg and the cracking it open to look for blood or something developing. so my question.... how long do you think i should incubate? i was thinking 5 days . too short??? what do you think??
