I asked the vet why the gamekeeper can legally release 2000 pheasants a short distance from us and yet we have to shut all our birds up. He just shrugged and said " different rules".
And PK, I did question the roofing situation but the vet said it has to be waterproof. We can't use tarpaulins here - too windy - which only really leaves the corrugated plastic option for outdoor pens, which isn't durable long term, or stuffing all the birds in a stable (not doing that).
Anyway, surely the very act of shutting birds inside contravenes one of the Five Freedom rules, the one that says they should have freedom to express natural behaviour? Geese can't graze in a stable!
