hi new user here so be gentle!!
had quite a few chicks dead in shell last season book said humidity was too high does any one know what the correct level should be?
also looked all over to buy some of the humidity test strips but can't find them any where any ideas.
its so frustrating to get so far and then loose them at the last stage
hope you can help  oh we use a brinsea incubator |

| I too use Octagon 20s, check the eggs for fertility at 10 days and transfer all the fertile eggs to a Polyhatch at day 19. Most of the fertile ones will hatch, the odd one or two have the big air space you mention and I fail to see how it can be a humidity fault when the rest are OK. I have decided that some shells are more porous than others. I simply follow the instructions for the incubator and refuse to fuss about humidity. A hen doesn't always bring off a complete clutch either. |

| It depends on how many days the eggs have been in.....usually 75% open |

I assume theyre talking about making the surface water in the inc increase to get the humidity up ? Like putting absorbant material in the water channels ?  |

we use thermometer strips and someone mentioned that you could get a similar thing for humidity.
we don't actually add any water to the incubators till the chipping stage any way so it was just to find out what the levels were to try and beat the chicks being dead in shell cheers for the link
the problem seems to be humidity to high according to the book!! |

A lot of people do not seem to realise that humidity is as crucial as temperature. To this end you need a hygrometer. The ebay link was to a reliable and accurate thermo hygrometer which you simply place on top of the eggs in the incubator so you can check levels quickly.If you have no way of accurately measuring the levels you will continue to have dead in shell chicks which is a pity. |
