duck eggs

[sadsak]

Our Millie is sitting on eggs again and it has been at least 35 days. Some of the eggs look black inside. What could this mean? Full of a baby or dead? This is the second time we have had them sit of eggs for 35+ days equalling no babies? What are we doing wrong. Trixie just started to sit on eggs last week

Hmmm... The only ducks I know that have a 35 day incubation period are Muscovy ducks. Others are usually 28-30 days. Have you candled them about a week after incubation/brooding started? Maybe they are not fertile. Mine are new layers and we are not sure the eggs are being fertilized.

I guess they are not fertile. If they are anything except Muscovies they shouldn't take longer than 29 days. How old is your Drake? Some males are aggressive maters and some the conditions have to just right. Do they have swimming water? Some will only mate on water. I've had 3 batches this year hatch fine but 4 ducks and a goose that sat on duds. I've got 2 on the go right now that are OK and one butterscotch call duck that decided after 6 days this was no fun and she'd rather go swimming and play with everyone else.

I believe our drake is over a year, and our ducks are a couple weeks younger. I'm not sure if he's an aggressive mater, but I've seen them mate in both water and land. They have a swimming pool that they swim and bathe in, and sometimes drink the water (gross). We are incubating our first set of eggs. We just decided that we'd rather keep the eggs coming instead of waiting for the ducks to sit on and raise the ducklings. We should be able to candle the eggs soon to see if they are fertile. I'm excited.
