Which duck is best? Call, mallard, or pekin?

[FireTigeris]

None of it is true or commercial hatcheries would do it all the time.

Why hatch 50/50 when one gender or the other is preferred 90% of the time (males for meat breeds and females for egg breeds)

Well there's a lot of conspiracys about making ur hatch male or female that are worth a try. Like higher temperature lower humidity, etc.

Are genders not set at 'conception'?

 

[mrpekinduck]

I'd honk any of it's very true but it could be worth a shot

Are genders not set at 'conception'?

Yes but if you make the conditions -bad- enough you can kill the embryos that are developing, however which embryos or if gender matters at all is the problem.

Idk. I'm hatching button quail this summer so I'll try some techniques

The only bird species I know for sure is affected by temperature ranges is the Australian Brush Turkey. There have been a few other studies from various species but I don't think any had conclusive evidence.

Well based on the fact that birds are genetically defaulted to male, any fooling around should kill the females first if the females have a weak gene where the male has two genes.

But that's an educated guess, one of the mallard hatches was almost lost, only 20% hatched and all of the ones that hatched were male... the water ran out day 7 and day 14 and was low day 23 and the temperature spiked to 108 for an unknown time and there was a power outage ("hurricane") for three days in the middle of lockdown/hatch and we 'broke in' (the school was closed for the storms but maintenance was there) and wrapped the incubator in towels and chemical heat sticks.

Wow ur really smart!
