Squirrel problem

gardener

i have three squirrels that come daily to my garden,ive made them a wooden feeder box,copied from the rspb design in their bird food advert booklet,i buy parrot food from local hardware store,this is mainly sunflower seeds,corn,peanut mix,they love it,also like digestive,choc/other biscuits etc,just cheap value ones,sit on the fence and eat them,they wait for me to put them out,done this for few years now and they do not now touch the birds food or dig up my tulips/crocus bulbs to eat,theyve realised they have plenty of food in their own box,They may bury nuts /seeds in the garden and had lots of the sunflowers come up last year,each have their own character and really do cry if they are in danger
