The wildlife attractant aspect remains as important and particularly in R1 Zoned urban areas this will be a problem…counter to all the efforts of Bear aware.
You can put your chicken coops in the equivalent of Fort Knox but the bears and coyotes will still come sniffing around . And, one successful break-in due to lack of vigilance will undo years of work by B.A. preventative measures. Any meaningful trial will restrict householders to about five hens. Their efficient egg laying lifespan will be about four years and then they will have to be replaced to ensure continued “food security”.
Nowadays it is technically illegal for ordinary people to simply bonk the birds on the head. They will have to be euthanized (legally) by a vet…..costly. The type of chicken food for the best production includes fish-meal and this is smelly and not cheap.
A meaningful trial should involve full permission from neighbors on both sides of the property, otherwise there will be battles which could get nasty!
LEAVE CHICKEN REARING TO RURAL AREAS IN OUR VALLEY and buy your eggs from them. Such a “can of worms”, I think.
Oh yes, for the “educational experience” of the kiddies, have them watch their pets be put down after four or five years!....Hmmm.
