For the last week or so, everytime I let my birds out to loft fly, they act like they have lost their minds. They fly around, dive between the trees, buzz the loft, it looks like they tumble and do rolls while they are diving at the loft. They fly away for about 15 min. and when they return, they do the same thing. When they come in for a landing, they come in so fast, it looks like they are going to crash just before they fold their wings and touch down. Maby it is just the good weather or something. Anyone else have the same antics?
