Well, I'm not a real statistician, but applying a two-tailed binomial test to the results at the time of this post (84 female, 74 male), I get a p-value of 0.4741 - in other words, it's not at all unlikely that an 84/74 split in a sample of 158 could be the result of chance with a true ratio of 0.5.
In order to conclude that the real probability was something other than 0.5 in this sample size, we would need to see at least 92 chocobos the same sex for the p=0.05 significance level, and 96 chocobos the same sex for the p=0.01 significance level.
Of course, this doesn't mean there couldn't be a slight bias, but if there is a slight bias, you'd need a much larger sample to be certain of it.

The stats seem to have evened out to the logical 50/50 chance, at 123 M to 120 F. This doesn't discount variables such as egg temperature, phase of the moon or whatever, but the simplest explanation is the use of a random 50/50 chance upon hatching.
