Used but great condition No Wheat Wild Bird Seed Mix (Surbiton KT1)

I mainly have a family of House Sparrows in my garden (who are selective on what birdseed they can eat). The seeds that fall on the ground (which are many) are being mopped up by pigeons and this is a problem with a small garden as part of a block of flats. I remedied the pigeon problem by creating a mesh cage underneath the feeders (see photo), but the sparrows and other small birds will not eat underneath it. There is a huge amount of waste! So, I have collected the No Wheat bird seed (dry) and placed back into the sack. There may be some soil and small stones within it. Otherwise it is perfectly suitable for ground feeding birds. Moving forward I have a more specialised mix on order that biases the sparrows and will greatly reduce the waste. Look out for a small back of fresh mix being placed on Freegle next week as the new bird seed arrives. Many thanks for reading.
