I have a feeder setup in the back yard. I would like to move it to the other side of the yard, about 150 ft away. It will be in clear view from the existing location. I am wondering how far I can move it at a time and not confuse the birds. It is winter here and they have become dependent on the feeder and I don't want any to go hungry. Can I move it in one shot? Or should I do several smaller distance moves?
