Why so many roosters?!

[Mischiefmaka]

As Ridgerunner says it may simply be bad luck.

There are two things you might could do to alter the outcome of future hatches.

The first is if one rooster fertilized all of the eggs of the previous two hatches try a different cock bird. Sometimes a rooster throws more males than females.

Second if you had a lot of eggs that failed to develop or that quit part way in those last two hatches you might try lowering your incubation temperature a few tenths. It may be that your box is running a bit high which is resulting in the eggs that would have been female expiring. Male embryos are somewhat more heat tolerant (to a degree) than females.

Of course you may have had more than one unrelated rooster fertilizing your eggs and your box temperature may be just fine. But possibly one of those could explain it somewhat.

For what it's worth I normally hatch at least twenty five at a time and I've yet to get a perfect 50-50 ratio. It's always been off by a few (as in more than one) either way. Haven't been way off, but never a perfect 50-50 yet.

Hens dictate the chicks gender not the roosters!
