Just wanted to share our most recent hatching experience. We recently started raising Jumbo Coturnix. We began by hatching eggs bought off of e-bay. Those first birds have been laying for a while now and I decided to add a tray to the batch of Black Copper Marans eggs I set three weeks ago. I set a tray of 20 Coturnix eggs in the incubator three days after setting the BCM's. Well, after having poor hatch rates with three batches of eggs shipped through the mail, I am very happy to report that of 20 eggs set we had three duds, four still in the bator, and thirteen hatched. So happy. In our last batch received through the mail, we ran 109 eggs and only 35 hatched. Prior to that, our first batch of 90 eggs netted 40 hatches. Hopefully we'll be able to ramp up our egg production to support this addiction! As far as the BCM eggs, not much so far. Fingers crossed we have atleast a dozen live ones out of 34 eggs. Needless to say, a better incubator is on my wish list as well.
