I found our aracanas the best layers and the eggs were good, bigger yolk than our others or the shop ones. Is was a rarity for them to go broody and usually just the same one did, other than once.
Then we bought on the spur of the moment 3 hens, all New Hampshire cross, so australorpX, leghornX, rhodeisland redX. Didn't have them long and they were all going broody and sending the aracanas off too... Mum now has the australorp, she went with her 10 chickens (9 were roosters) and I'm going to get 3-4 aracanas when the yard is ready for them (no little moos in it) because they just worked so well.
If I was closer to the battery hens I get them, as my experience they are good layers and nice calm chooks.
Only thing is I don't eat my hens, so the aracana aren't for eating, I think there's still a lot of jungle fowl in them
They can fly a good distance, perch high in trees but in some ways that's good for foxes (none of which we've seen mind).
