I have looked at the eggs again today and think i can actually see a mass with some veins so am hoping they are good. Heres hoping. Mum is sitting all the time now. Excited.
My other duck has started laying now but there is obviously no room for 2 in the house so she laid in the pool bless her. Have sorted out a little house of her own today so now she is quite happy. Her eggs are very different though, longer and a very pale green colour. As i am not sure what breed she is i am assuming this is normal to be different.
I candled the eggs again last week and could see veins very clearly. I am not sure of when they are due to hatch though. The development was certainly different to when i first did it. There is only a small air sac i think you call it visible now. If i have worked it out correctly i think hatching time will be next week.
