Some of my visitors today

Blue tit, chaffinch, dunnock, goldfinches and pigeon in the collage but I also had robin, wren, great tits, coal tiits, blackbirds, long tailed tits, jackdaws, magpie and jay.  Has anyone else had a problem with their fat ball feeders.? Mine haven't been touched all winter - I have changed them over to different ones.   My peanuts have gone mostly to the squirrels and jackdaws although the tits have suddenly found them today
