I live in the city and my aprx 1 yr. old sexers refuse to be kept in by our 6' fence. I didn't want to clip them because they like to sleep in the tree. Unfourtunatly, our neighbors aren't so found of my girls. I stupidly read the wing clipping how to too fast and ended up clipping both wings on each bird. Is there any other way to keep them grounded other than a full enclosure? How long before I get a second chance at clipping?
