@stibbons With me the issue was that the hook would grab the chain it was pushed through, splitting the yarn. Solution? Much looser tension. Twist hook as you pull it through so it is pointed at the base of the chain instead of the side. Use better yarn.
@stibbons This is a red flag. Since you’re doing a practice swatch, practise making a really sloppy (by your standards) opening chain. It’s hard to undertension crochet IMO.
@stibbons If it’s any consolation, the more of your work you get to hang onto, the easier it is to work with. I always find that first slip knot infuriating, and the foundation chain not much better.
