Hi All,

The mixed setting of duck eggs which was set from the start into the trial unit has now hatched.
The setting contained Cayuga, Blue Swedish, Indian Runner & Saxony eggs. Once clear eggs etc had been romoved we were left with 29 eggs which appeared vaible at day 25.
Of the 25 we successfully hatched 22 ducklings - 75%, which in anybodys book is a more than reasonable result for duck eggs.
The unit certainly has far better humidity capability than the old model & overall I was very happy with its results.
I am sure that with a little tweaking to the incubator setting I could get an even better hatch rate.

In fairness to the test, there were also 12 Black East Indies eggs set, but they have not been included in the above numbers. Everybody I know who has purchased these ducks has had major problems with hatching (as DannyB will attest to). Of the 12 set we hatched 2. This is one of the better weeks!! We often get either 1 or none and over the course of the season, setting up to 14 eggs a week, our best to date, in one setting is 3 ducklings. All the birds I know of are from the same source. we are now going to try natural incubation for them & see if its the birds or incubation process with the problems. Fertility rate is great, but the ducklings seem to die in the shell at some point between week 3 & hatch time. Typically 1 or 2 more will pip but not hatch.

This week we will also give Bob's new humidifying pump a run to see how it performs - with the heat coming it will be very interesting. Tuesday has a top temp in excess of 40oC predicted.

Yesterday, I tried one of the new humidity pumps in a standard Greatlandr 4TTH of a mate nearby.

It was mid-afternoon, hot and dry and the usual `see-saw' in humidity was going on. (His ventilation fan is still set as an exhaust).
The fan was coming on quite frequently to regulate temp, and expelled with the hot air of course went the humidity, which is airborne
The humidity then had to be re-made as vapour.
He was mid-hatch with about 150 Jap Qual hatched and about 50 still to come out, so there was no alternative like unplugging the humidifier.

We fitted the humidity pump over the edge of the water tray with a small clamp and topped up with 250mls of cold water (the water in the tray was hot to touch)
We went inside for half an hour and when we came out again the RH was up where set and the fan hardly came on at all
The `pump & misting nozzle combination' seems a far better option of creating large and controlled amounts of humidity in the hot dry weather we're having.

Getting great hatch rates under the parents so far with 2 more ducks due to hatch clutches soon. The little buggers just don't seem to like incubators.

We now also have 2 BEI ducks sitting on their own eggs, but still a while to go before hatch time.

It would be neat to sneak heat, humidity and motion sensors under one of your ducks ... If they won't tell you what they're doing :ROFL

Too late - they hatched this morning - 12/12. The other clutch is only a couple of days behind,

I had a very interesting call yesterday from a new Greatlander-owner in Alice Springs. Peter M.

His feedback is about his one-week-old 5TTH Greatlander Top Hatch fitted with dual methods of making humidity (element and pump)

Yesterday when he rang, Peter said it was close enough to 40oC in his shed (outside it was 37oC and Humidity 20%)
His Greatlander was stable around 38oC the Set Value (Temp was very slow-moving he said, and maxing at 38.2)
Humidity however was very mobile, hunting around 50% the Set Value, but coming on quite frequently
He said he just had to tell me that he was thrilled his set was running cooler than the ambient in his shed

Peter's set has its vent fan reversed - to act as an inlet fan - but there was no fan activity.
There was no heating activity nor any fan activity whatsoever.
He said all his vents were open.

The only activity was the `Wet' - energising the humidity pump
So was it the micro-mist keeping the heat lower than the outside?
Any thoughts on what might have been going on system-wise Greg? (vents leaking moist air out, is that a plus or minus, etc)
In particular, what do you think would happen in humid and very hot weather?
It seems that DRY and very hot weather is taken in stride from what Peter says.
