Trees

looks like a hybrid …

I know a lot of breeders of things like canaries quail etc use conifer but their birds are not chewers like parrot species. The sticky pitch that is produced from the sap may be an issue with feathers etc …. plus the term conifer is a group name not a species name … :thinking:

Leylandii does contain isocupressic acid, which has cause miscarriages in mammals such as cows and other some other livestock when consumed in large quantities ie not just a one off mouthful but something to graze upon and chew. The oil in the tree can also cause skin irritations in some sensitive humans... red blistery rash and really really itchy.

For me personally … all I can say is ..... I throw my hands in the air in a shrug jury is out for me…
I wouldn't use it but can't find a concrete definition anywhere hence deciding to air on the side of caution. :confused: sorry not much help :(
