First time hatcher

[Mountae]

So a bit ago I joined asking about duck laying as my two lovely Muscovy’s had bred. Luckily she began laying a couple days later and has since been laying everyday (which is incredibly good for her so she’s one very happy girl).
Because of all the dangers (we live in the NT Australia) from snakes, birds, Bush rats, and even our own dogs, we ended up grabbing the eggs and incubating them ourselves so they were safe.
they Have gone amazingly ! They are now on day 29 so I have a few questions for a first time Hatcher

1. when should I expect pipping, I heard it’s different for each kind of egg but from what day is it more common to start to see them pipping?
2. How long should they stay in the Hatcher after they have hatched? Until all have gotten out of their shells? Or a few hours after the last one has gotten out?
3. When should I help if any problems arise? I heard it can be a slow process and to be patient but when do an eggs chances dwindle of actually being able tk hatch without help?
Any and all advice is welcome and thanked!!
Thank you in advance

Hi, I haven't hatched any ducklings but have hatched lots of chicks. I leave my chicks in the incubator until most of them have hatched, I used to remove them once they've dried out but by opening the incubator numerous times during the hatch I greatly increased the chances of chicks getting shrink wrapped, it has happened a few times to me and sometimes I've helped and the chicks have been fine but other times I wasn't able to help and the chicks didn't make it. On my last hatch I had 13 chicks hatch before it got too cramped and they needed to be removed, I draped a towel over the incubator, quickly removed the chicks and placed a wet sponge in the incubator. I only felt comfortable opening the incubator because the humidity was 80+, the rest of the chicks hatched fine and didn't get stuck. It is a very slow process but I've found its best to be patient and not rush in and try and help because it can end badly, I made that mistake once and will never make it again. Hope this helps!
