Well if they are all boys, how much success would I have if I tried to integrate them into an existing, mature flock of hens: 5 Jersey Giants and 1 odd-ball (see my avatar)? Maybe introduce 1 and find other homes for the other 2?
Oh, the reason for my concern is that the trees that they roost in is on property "For Sale". I was going to contact the Real Estate agent and see what's up. If they are seen as a problem like devaluing the property or the new owners don't want them, I was going to do something. Otherwise, they seem to be a fixture in the neighborhood and fend for themselves quite nicely.
What's totally fun is to take a look at the property using Google Maps. The address is 4873 Eldred St. LA 90042. Punch it up on Google Maps and take a look. I was hoping the camera shots showed the boys roosting in the trees or hanging out, but alas they ar not in view.
