When we hatched eggs recently, we had some difficulties maintaining the humidity towards the end of the hatching process. We were told the unstable humidity could have caused us to have more males. In our case we ended up with 4 cockerels. Just wondering is this a myth or has anyone had similar experiences? Thanks for any help. P.S. We used a Brinsea Octagon 20 Advance Automatic Egg Incubator without the humidity pump.
