I have 30 gold sexlink chickens that are almost 20 weeks old. We had a part of the backyard fenced off for them (some lawn, some dirt) until the garden was finished and now they have the run of the whole back yard. It is fenced and they were fine until lately when they seem to be playing "who can fly the highest". We have found them on top of the grape trellis which is taller than me and from there several flew into the front yard. They don't go far because once they are out, they realize everyone else is on the other side of the fence and they scurry back and forth trying to get back in. Today we looked out the kitchen window and saw one on top of a different grape trellis and two on the shed roof beside the trellis. When we tried to shoo them back in one took flight and ended up in the neighbours yard. My concern is that several neighbours have large dogs and if the chickens land in their yard they will be lunch for the dogs. I don't want to clip their wings (I've read about it and am not sure I can do it). They have not been handled very much so only a few of them are tame enough to catch with any ease. I'm wondering about some posts about training your birds. Do you think I'd be able to train them to stay down? If so, any ideas how to go about it? Please help.
