I had the problem of the wee birds getting nothing and the big birds scoffing the lot and bullying the wee ones. It cost me a bit to sort it but sort it I did. I have a Feeder Station with places for 3 hanging feeders, a feed tray and a water dish. I kept the peanut one as it is and replaced the seed one and the suet ball one with Pest Off Feeders, they work a treat and the big birds can't use them. They have the Peanut one and the tray feeder, everyone's sorted and happy now, all get their share.
