If you have been allowing your bird access to snuggle huts, don't. Snuggle huts are extremely dangerous for other reasons as well, but definitely contribute to hormones in the vast majority of users...same with tents, coconuts, under tables, in bedding/blankets, piles of paper, shadowy spaces etc. They should have no access to shadowy spaces as these spaces are preferred by them due to nesting tendencies and the presence of such spaces amplifies their hormonal response/triggers them and can also make them more territorial/cage aggressive.
