hey all
was just wondering if u can have too much humidity in a home-made bator??
like would it be possible to have the whole floor of the bator water as they do this with python eggs and it works but not sure if it applies to chooks??

Yes you can have to much humidity. The whole thing about humidity is that the egg must lose moisture at a given rate to make the air sac bigger at the time the chick needs it to breathe.

Jmac,

At 100F (37.8C) the relative humidity should be between 49% and 54%

I tend to leave my humidity at that setting all the way through.

Jmac it really depends on a few factors, your eggs, your anbient conditions and the incubator
I personally aim for 55 % for the first 18 days and 75% for the last 3 days. This works for me, but it may not work for you.
Observe each hatch and work out what works for you
.

Regards
Trev

Try calibrating your hygrometer Dave, viewtopic.php?f=6&t=7970593, I was always happy with 35% until I found out both my hygrometers were low. Now I am happier not worry about about readings too much. I suspect that I get better results with readings that are a lot lower than those needed for foam ones.
