I have 38 that are still in the nest all around 10-12 days old, I'm not planning to keep too many for myself this year so these Ybs are already promised to a few fund raising charities and the rest are being given to friends.
Had mine away today for a 25ml toss and for the 3rd time this week they have been well apart on their return but at least their having to think and navigate after a bop strike. Luckily I have just had my last bird return just now so hoping for a clear run tomorrow without the bops
