Pick a number, for example, 218. That means you should have 218 icons in your friend bar to unlock the bin. If you have less (let's say 200), then you will see "Need 18 more friends to unlock)". This message is influenced by your friend bar and if Hay Day has issues to retrieve friends from FB/GC at the launch of the game, the number changes in real time. if you add all your Friend in GC and the number of fr needed + 1 (Greg) + number of farm you follow, probably you find one of those numbers listed.
By the way, what I got is from 1 year ago and could have been changed. Just wanted to share.
EDIt: my friends are gone, there are Greg + 3 followed farms = need 215 new friends -> total 219 required. (17 bins now, included at least 1 with diamonds)
