Absolutely it does... was getting maybe 20% successful hatch from lockdown using an auto turner... switched to hand turning and got 24/28 successful hatch at lockdown, 2 I was certain wouldn't hatch though but left them in just in case...
I turn at least 3x a day, 5x if I remember enough...
SC's, no contest...
My eggs took a nice jump in improvement from last year... I'm happier with them, but I'm my own worst critic, lol... even my older hens eggs look bluer this year...
You started with all of yours direct from PS, you're birds are fine... plus since you got chicks from multiple pens of his, your genetics should be just fine for a few generations at least...
I started with mine from someone who was getting out of Am's... theirs were originally from JB, but they had been breeding them themselves for a few years... luckily, they did know what they were doing so they're good stock, but nowhere near the level of any of the current major breeders... plus I needed a new roo since I refused to breed their brother to them... after the last year and a half looking for a decent roo, getting one that turned out no good, I should be set now for quite a while as well... will see how this generation turns out and go from there...
Nope, you shouldn't...
