Low Hatch Rate

[pebbles13]

We have recently bought a genesis 1588 incubator and have hatched a few batches now, but our hatch rate seems to be decreasing, not improving.

We have done a lot of research, and think we have most things right, in regards to temperature, humidity, storage of eggs, etc.

We are getting our eggs from a local, who hatches on a mass level. His setup is quite manual (ie. turns by hand and temperature control is a bit dodgy!). Yet his hatch rate is quite high.

In any one batch, our problems range from: hatching early; not hatching (but when we break open a few days later, dead birds or under developed birds); and difficulty hatching (eggs pip, but bird struggles to hatch).

Any suggestions or tips greatfully received!

Thanks

Early hatches mean the incubator temperature was a bit too high. Too high or too low temperatures can also kill developing embryos. I'd suggest you try a different thermometer, double check your humidity and calibrate your thermometer. Some how-to guides here:

Thankyou very much for your advice. We shall certainly check the thermometer. As for the humidity, we fill the water compartment (as per the instructions), but do you know what it actually should be during the rotation stage and non-rotation stage?

Cheers,

There is not a set number for humidity, but I personally get very good results incubating at 45%-50% humidity during the first 18 days, after which I increase it to 65%. A hygrometer is a good investment when you incubate eggs and it need not be an expensive one. I bought a cheapie at a pet shop and it's been working very well for me. The thermometer on the other hand... Rather spend a bit extra
