As I read this and had the "Aha" moment I could almost feel my long-deceased grandmother doing a forehead slap and saying "Child, we had to eat!"First batch of Dels is 4 pullets out of 12 . so thats about what I got 75% .
When you figure use as Heritage / Old homestead that wouldn't be bad as you don't need but so many eggs to eat/hatch. Most would go for table fare and the Cockerels are larger for that purpose.
Second batch is 5 pullets out of 14 so thats about 65%
Now it makes perfect sense. Of course you would want lots of big fat roos around for the pot.
Don't worry grandma! Your city-girl grandchild is catching on slowly but surely!
