Ducklings pipping 3 days early.

[Jetblack2004]

I have an Brinsea Octagon 20 and we are hatching out some Khaki Campbells in it. This is the second time we've hatched ducklings. The first time the eggs pipped on day 25 and hatched in day 26. Today I went to take the eggs off the cradle ready for our second hatch of ducklings and there were lots of pips and one even with its beak out of the egg.

I'm wondering why they are pipping.
1) Could the temperature be wrong?
2) Does the Brinsea hatch ducklings quicker than the duck or other incubators?
3) Do Khaki Campbell ducklings have a shorter incubation period?
4) Instead of 28 days incubation does it actually take 26 days?

Thank you

I would guess that your thermometer is incorrect and that the incubator is running slightly on the high side.

Them hatching early would indicate high temps. Did you calibrate your thermometer(s) before you got started, or are you relying on the thermometer that came with the incubator? I know Brinsea states that they calibrate the instruments before they send them out, but those instruments are often wrong still. Always best to have at least one extra (calibrated) thermometer to double check your temps.

Khakis should take 28 days to hatch.

Ok. The only temperature thing I have is the one that comes built in with it. I will buy another temperature thing.

Thank you for replying

We're on day 29 with a brinsea mini with campbells - they're 28 day hatchers.
