I have noticed a difference in my settings lately- and I am now incubating in our winter- meaning that the heater is on inside the house- Great for the ducklings- But I have wondered if it could be effecting the humidity. I have noticed that I have to refill the water trays more often recently - so I decided to try increasing the humidity a few days early with this lot of eggs to see how things go. So far I have 4 internally pipped ducklings from 8 eggs on day 26 - Nothing out of the ordinary there..But I am hoping that this hatch will be a little easier than my previous two. I have had a few pip backwards lately- which could be a sign of not enough moisture meaning the duckling cant turn and tuck the right way- I know it can be an indication of a lot of other things as well though- But thought this is at least one thing I can try. I have been misting these eggs every few days- as I do with every hatch - they were in an incubator with a fan - rather than still air - however the hatcher where they now are has no fan. The aircells on every egg were at a good size- so I wasnt worried about any duckling being at risk from drowning if the humidity was too high for an extra two days right at the end of the incubation period. They went into lockdown 48 hours ago- and the official time for being "due " is about 42 hours. I increased the lockdown time from 3 days to 5.... I will be watching this lot with great interest..and will post about the results and comparison to previous hatches.
