Fat Balls still in their nets

Do you hang fat balls in your garden still in their nets?

A few years ago when I started feeding the birds in my garden I went outside one late Sunday afternoon and heard a bird which sounded as though it was in distress. I walked up the garden not knowing what to expect and was greeted with a Greater Spotted Woodpecker entangled in the net holding the large fat ball . I rushed to it and held it and it started to peck at my hand, I turned toward the house and luckily spotted my hubby at the back door. I shouted for him to get some scissors. Hubby managed to cut away the net from the birds claws and I opened my hands and the bird flew away to nearby trees. I thought that would be the last we saw of him but we were so happy when he returned the next day to eat fat out of the proper fat ball feeder we had  just purchased. Each time I buy fat balls now I always take off the net before putting them into the feeder.
