If you have one of these, please do not use them. They have been recalled, as birds are suffering their death ,as you see.
It seems that the 'Peckish' brand of seed offered free feeders last year along with a packeet of fat balls, they were in yellow plastic boxes.
These were later on a product recall as they were harming birds, but some are still being used.
Peckish said they sell over 430,000 feeders each year and this is the first time it has happened. They say anyone who still has one of these free feeders needs to contact their customer care line.
