I have about 35 pigeons coming every day to feed at my feeders,many pretty unusual colours,but the one all white is beautiful.
I understand how your husband feels,some people however think of them as more or less vermin
Are you sure they are not doves??I had a Ringed Turtle Dove at my house last summer,they too are white and quiet large.
I hope you find a solution for them
Here's a pic of some of mine,not a very good,but you can see the white one.
Good Luck!!
