I currently have 4 muscovies on nests. I unfortunately lost the paper that I wrote down the 'broody' days on, but I know that three of them went broody approximately at the same time, around 4/9. One nest is only 6 eggs, the other two are about 12-15 each. I should get a better count one of these days, but I hate messing with the hens too much. Then another hen went broody on a communal muscovy nest, with over 30 eggs in it. I think I left her with 31, after removing broken or dirty eggs. I'm fairly certain I'll be paring down the number she's got over the next few days, as I check and make sure she's covering them. The three nests are due approx. 5/14, and the fourth huge nest is due to hatch approx. 5/29. I love spring ducklings! Now I just gotta sell 'em all.
