Net washing was being undertaken at time of inspection, this resulted in reduced visibility in pen 4 during cleaning, but no dead, moribund or lethargic were observed.
Bird observed in pen 8, site staff took time and care to raise top net and guide bird out of the pen, before dropping the top net and checking that the net was securely in place.
