I was thinking that perhaps I would eventually just throw these birds in with my free-range egg layers (I haven't free ranged any birds yet but that should happen this summer when I finish the coop area in my barn). They might be wild enough to be good free-rangers but so far the number of eggs is so low. I do think that they are just starting to lay though. I've gone from just the occasional egg to occasionally having up to 3 (out of 5 hens). I have an Ayam Cemani X Sumatra that I got with the regular Ayam Cemani and I KNOW that she hasn't laid an egg yet because I have her in a separate pen with a Ceylon Jungle Fowl hybrid rooster. I don't think that little rooster can breed with any of these large fowl hens unless they REALLY want to...and so far I don't think any of them want to!
Lol! The girls can be very intimidating to a smaller or less secure rooster for sure... they have very strong personalities no doubt...
For free ranging, they are absolutely excellent... very predator wary and flight capabilities excel beyond any other breed I have had... egg laying is definitely not what they are best at though... mine lay exceptionally well WHEN they lay... 6 eggs a week per is not uncommon, but they go broody A LOT and take laying sabbaticals at various intervals...
