so on the 14th, I set a single mallard egg from one of my girls. so it's been 10 days, I don't see ANY viens, bu then I don't have any experiance with darker shelled eggs, when I compare it to another egg tat has not been incubated, this is what I see. the unincubated egg I can see right through it. the egg in the bator has what looks to me like a dark "belt", the air sack is taking up about alittle less than 2/4 of the egg, and there is a little dark mass that moves when I rotate the egg,it's not stinking yet, wich i figure it would by ten days. I will try and get pictures at some point when I can get someone to help me. but until then what does it sound like??
