I'm on my first Turkey hatch from my own eggs, set 11 eggs and 10 developed. One hatched last night, 4 more are pipped, so we'll see what the end result is. I run two incubators for staggered hatches, 99.5-100.1 is the range they've been running at, a Hovabator fan model for incubation and the Sportsman with fan for hatching. I have two more batches of Turkeys going, due the 17th and the 5th. I aim for 40% humidity during incubation, but it ranges from 25%-50% depending on the water level, runs higher when I refill it, dips when it gets dry.
This batch hatching now I expected last Wednesday, so either I did bad math and something caused them to take longer. Didn't have any power outages or temp issues, so I'm guessing bad math.
I was worried about a poor rate for the first batch due to winter rations... the adults weren't getting greens yet and they were on a 16% layer feed with the chickens, with game feed mixed in once the temps started warming. Now they're getting Turkey breeder rations with daily grass so I'm curious to see the difference.
Have hatched tons of chicken eggs, but have only ever raised well started poults (after that 2 week in age mark) Unless I'm using shipped eggs, I normally see 95%+ hatches from my own eggs.
The fan model incubators have proven to reduce hatching issues dramatically. The humidity regulates better, stays more consistent. When I was using a still air, running it low on water helped. Filling the tray as directed made it too wet and there were issues.
With the diet the parent stock was getting when they first started laying, I have vitamin water and gamebird starter ready for these once they move to the brooder.
But yeah, the only time I ever had a hatch rate as low as 27%, it was from shipped eggs. Diet of the breeding stock matters much more for shipping eggs, to make them "sturdier" and more resilient during transit, unless the box just gets shaken enough to scramble them or detach the air cells.
Is your hatch rate from one batch, or has it been consistent?
Right now we have 2 pairs, separated to keep the toms from bickering. We worked in breeder stalls into the barn, so each pair has 5x6 inside space and 15x25 outside space.
