Two of my muscovy girls have layed eggs (13 in one nest) & (8 in another nest). The only problem is that they only sit on their eggs in the evening. Their "sitting shift" starts about 7pm and ends at 7am. I have NEVER seen anything like this before. The temps here in Louisiana have been as high as the 70's, so it's pretty warm during the daytime but I am concerned that the eggs won't hatch because they are only on their eggs for 12 hours a day. Has anyone else ever seen this? Is this normal? What do you think the chances of the eggs hatching? What do you suggest I do? Why are the ducks doing this?
