I am not familiar with that three, despite not being far from you down here in RI. Assuming it's not toxic to chickens (Google around, but it's likely not), small leaves in the coop is probably better than big leaves. The key is to make sure they're very dry when they are added to the coop.I have a similar question, are leaves (small leaves not like oak, they are from beetlebung but you probably don’t know that tree) good as coop bedding? Not in the run but in the coop. Thank you!
