TBH, dal, I do not feel I need to expand on it. IF the fly aways aren't caused by predatation, as I said IMO it down to over crowding, it is seen in nature from the rock doves on the rocky cliffs, and many years ago I introduced a new strain, and I wanted to breed as many young from this family as possible as a result I suffered with fly aways consequetively for 2 years. The 3rd year I reduced the numbers drastically that I bred, and touch wood I've never had a fly away again.
