I asked this in a seperate thread, but it's not getting any answers so I'll ask here. It's more active
How many eggs should I incubate with the intention of getting 8 chickens? (7 chickens, one rooster) My eggs will need to be shipped, and so I'll expect at least a 50% mortality rate there. That makes 16. THEN I have to account for the 50% likelyhood of getting roosters instead of hens, so 32 eggs. 32 eggs for 8 keepers seems high. What say y'all?
I would say your math sounds about right bit I would round up a few. Better to hatch a few too many and sell the spares on CL than too few and be trying to hunt for chicks on CL. But then again, I am a bit chick crazy...
