I have the same configuration up right now, Doyd. I haven't seen any hummies yet this year but they only seem territorial around one another. They come and go so quickly, they seem focused on their own objective until another hummy dares to approach.
Try it, if the hummies avoid it, she can always change it up. I keep a flowering pot up there with the seeds, everyone seems to get along.
For every day I choose to play,
I set aside a day to pay.
