I've had my young birds out for the past few weeks. They batching very well and flying for 30-40 minutes around the loft. Left them out tonight and they was flying very low just above rooftops. 2 went into a wire which has never been a problem. And within 10 minutes they were back on the loft. They then went up again and lasted a bit longer by was still very low, they have never really gone high but never this low. Then a gosehawk appears and hovers around before luckily left my birds alone and disappeared. Just a minor hiccup? Could they have been scared knowing the gosehawk was around?
