Sal, better known as Higa D’Drip (formerly Every 1000 subs is one new video)[1], is a vlogger that focuses on uploading videos based around chickens and other birds in a backyard-like setting. The videos are under 5 minutes, and this channel mentions that for every one thousand subscribers gotten, there is one video uploaded.
There are community posts sometimes that mention the titles of each video which allow viewers to vote on new video titles, and there are often responses by the owner of the channel. The subscribers would probably be obtained from commenting on various different newly-released videos by popular creators and tending to be high on the comments section which makes his comments more visible.
