As for ethical-- I think if they are "doomed" to be shot by animal control anyway, why not use them for some good instead of just letting them rot where they fall? But unless people in your area are used to eating game birds, it might be hard to convince them to try something new and you may end up eating them all yourself.
Ethics are more personal. The question I see here: is it legal?
Ethics of meat of me is more about the way to raise them, and the global cultural way we have created, because it mostly implies that food production does not have to be ethical but just legal! And ethics vary, as we can see that some people want to force others to eat only plants, even though some people cannot.

According to the original post animal control has been ordered to kill them. Zero waste is one of the permaculture fundamentals.
Starvation seems like a public health issue. Lots of animals are "beautiful" but people eat them all the time. I would tell those who would prefer it just be wasted to get over it. Just because it's not wrapped in plastic doesn't mean it's not good food. I think it's time to think outside the styrofoam box a bit!
Argue for your limitations and they are yours forever.
If the peafowl can be captured one might consider "selling" them. Peafowl command quite a price, when you can find them for sale.... $400 to $500 a mated set is not an uncommon price. Just buying chicks can run you $20 to $25 a chick...
Some day I would like to get into peafowl, but for now the price is too much and with four teens still at home, I have my hands full enough with them at moment.
