In my neighbourhood, many people have Catalpa speciosa (Northern Catalpa) as an ornamental. It has beautiful flowers in the spring and has big pods this time of year. I was wondering if anybody uses those pods as chicken feed.

As an aside, how are the flowers in terms of pollinator "food"?

I would like to second Adrien's question. Has anyone experience with the seeds edibility for poultry?

No idea, but I do know that my catalpa collection produces copious amounts of catalpa worms 3 or 4 times a year, which would provide a high protein food source for the birds with easy collection (shake the tree, and they fall), a second income source (bait shops pay top dollar for fresh catalpa worms, and a few folks make a living selling preserved ones. Great bait) and bait for very successful fishing if you like. Strangely the chinese catalpa attract the most worms. It is quite easy to notice when the worms are on the trees too, the whole trees are stripped of leaves. A more direct and profitable use of the seeds would be to germinate them in gallon pots and sell in hunting/agriculture classifieds as what they are: catalpa trees (or possibly "catalpa worm trees") In other words, you could buy the chickens almost anything you want to eat, or more trees etc. with what you would get from just a few seeds, around here they sell for 4 or 5 bucks a tree for season-old trees.
