Temperature Sexing

[thaveteran]

Due to the recent A/C problem I dealt with earlier in the week (now resolved for a mere fraction of what I was originally quoted) I've been thinking about the whole temperature sexing thing.

Ok, so it's widely known that the sex is determined in the first 2-3 weeks of incubation. Now my question is, is constant temperature required during that period or can a short spike or dip somewhere during those first few weeks if placed at the right time affect the sexing of the leo in the other direction?

To make it easier here is a scenario. Say you are incubating at 83 degrees for female but you experience an increase up to 86 degrees for maybe 3 to 5 hours. Is that enough to produce males if it fell in the right stage of development?

generally that should not change the sex. the thing when you have fluctuating temps is the possibility of eggs dying or animals born with deformities. you want to try and keep the temps as consistant as you can. a degree or two +/- is ok but too many fluctuations through out the incubation time and too much of a difference in the temps an cause problems.
