Hatching duck eggs

[Peggy J]

My female duck was killed the other day and I managed to borrow an incubator from a friend the next day. Hopefully I wasn’t too late getting them in there. It’s been hot and they were well covered up in the chicken house. My question is: they were supposed to hatch about the 23rd of August. Will they still be on track for that timeline?

The incubation period may be extended a bit due to the period of cooling. Best wishes for a successful hatch.

Thank you. One egg had burst this morning but I could smell that one was bad and I guess that was the one. Do I just keep the temperature the same until they hatch?
