Hi folks, I'm new here and new to keep Muscovy ducks. I'm starting wonder if the two broody ducks are sitting on bad eggs after 7 weeks and no hatching. I don't have a candler, but used a bright torch to see if I could work out if there are ducklings inside. Some of the eggs were definitely not fertilised at the bubble moved about, so I chucked them away. One egg I was so uncertain and exasperated, not knowing what I should be seeing, so I started to crack it and there was what looked like a semi-formed duckling....but I was so horrified at what I'd done that I didn't continue to see exactly what was going on inside. I daren't do that again. The others look like some of the google images of good eggs....but the shells are so thick I can only see a slanting air pocket. In some the air pocket seems to be huge, nearly about a third of the total egg volume....I've not seen any movement in any of the eggs which I expected to see by now. There was a horrible cold spell a while ago (I live in the UK) and I'm starting to now think perhaps the ducklings started to form, then got too cold to continue and died. The ducks chose to sit outside, despite have two nice cosy huts to occupy. I put water and food by them so they didn't need to wander too far. Google says 30 - 35 days incubation....it's now 49. I know some eggs were laid after the initial brooding date I noted, but probaly within a week of sitting. Do I give up and remove the eggs? My little tiny hen sat on two eggs and I was surprised to see two little fluffy chicks yesterday morning...so quick and effortless compared to the ducks. Please help. I've no idea what to do.
