We breed moulted Java. They are beautiful upon maturity. Sorry for your loss. We have been incubating ours as well as broody hens. We have better success in a controlled environment. Us anyway. We also breed Wyandotte's and Barred Rocks and a little barnyard X's. But the Moulted Java's offspring are by far the most strongest and rambunctious of what we have. They are so docile.Went out to let the kids out this morning and found our Mottled Java, "Peepers" had not survived the night. This AZ heat is brutal. Even with misters, ice, lots of shade, wading puddles, fans, and frozen treats, it's going to be a very long summer.
Don't think I'll replace her though. I've got a hold on a couple more Isbars and a couple OE's that I'll pick up this weekend, and I've got a good number of brown layers now.
This past weekend, had a major humidity malfunction in our bator and had twenty or so Java's drown during peeping process. Horrible. Discarding almost 2 dozen heavyweight eggs full of chicks.
The hygrometer lied to us. The balance of the batch that wouldn't fit into the bator was placed under our broody hen and 4 out of 7 made it. Ups and downs of creating new life.
Again sorry for your loss and do know how you must feel. Keep trying!
