Birds aren’t feeding from my feeders

hi everyone 

I wanted to ask people’s advice, before my drive was concreted I had a bird table which birds did feed from, now it is concreted I’ve put 3 feeders on my fence and no birds come to them, it’s been 2 weeks now, there are birds in the neighbours tree, I realise the position isn’t great - do you think this is the issue, I can’t think where else would be suitable. I can’t use my back garden because of my dog.

thank you
