She laid another health looking 2 1/2 in from top/bottom egg. All 3 are the same size so far, a beautiful pale bluish green. Is that small for an egg for a mallard or Roun? I guess the best description of her is a dark female mallard. With the royal blue in the rings. No wonder the male was so mean and aggressive at 7am, at that time there weren't 3, just 2, 1 1/2hrs later there was 3. Now how long could this go on this egg laying? And is there any specific food to get during egg laying? The forage in the yard, but I get them like the 16% food, I thought I read somewhere add oyster shell when egg laying for harder eggs? I really do want to see what this 1st batch provides if any, call it an experience, learning experience. EWWWW, I just looked outside at the ducks cleaning themselves and other then Oreo(the female) laying eggs, and assuming Ming-Ming(runner) boy, he just confirmed it when I saw a very long pink twisting cork screw hanging out back!! I never saw something like that before, I just told my son he should have named Ming-Ming "Twister"! Ok, so my question is, what foods or something should I add? Should I buy an incubator w/automatic egg turner at Tractor Supply? How long should I let her continue to lay before either taking them away or intervening and getting a incubator and trying that method and then candling them? Have any of you had fertilized eggs and successful egg laying to a 1st time young mom? Why would my male be the aggressive mean one and not the female towards the nest/territory? Will my female turn aggressive when she starts incubation? (She is such a sweetheart, she actually is a good cuddler when my son brings her in and sits her next to him, she will sit there and actually rest her head on his shoulder.) When should I calculate incubation, from the day of her laying on them FT to 28-30 days or when she lays the 1st one but doesn't sit? BIGGEST question/concern: Since she was born with a birth defect of a raised leg as if she was holding it up, but it won't go down. What could the chances be of her offspring having defectiveness, especially considering the dad is a different breed? I see that she has been turning them, she moved her very 1st one when she made a nest for the other 2, and I numbered them and the numbers aren't facing the way I put them back. I'm eggcited, what can I say! I really want this to happen, and I really want this to be a learning experience for next time. I know she must have more eggs in her, before she lays I notice she seems to get fuller near the back end, and plop comes another one. She is a every 2 day egg layer. All 3 eggs have been laid every 2 days the 1st one was laid on the 27th. Sorry for the long post and many questions.
