Hi Paulo,
we have the same problem, I always know how many YBs i have, but next door they have about 50 ish, the ish bit being what ever goes in might be there for a week or so depending on the weather.
The 2 ybs i got off you are just starting to flutter round the lofts, Its been iffy at times to get them out.
Yesterday had them all out and about, then whoosh 36 out of the 38 were off ??)
Got most back by the end off the day, came in singles and small batches, but still have 8 missing, another 2 have just started coming for a look round so hopefully will get them in tonight.
When you start doing well with your YBs hopefully it will pi** off your neighbour even more, he may then ask what you are doing, to do so well.
Never to old to change in my opinion, got my dad trying different things and hes 74.
Dave
