I think you mean
3rd cut

which is the cut with mostly leaves, and I agree it looks like it could be 3rd cut hay to me too. If it is, it's not good for everyday feeding hay, but can be mixed in to encourage hay consumption since most chins like it, and can be good if your chin is underweight. It's much softer being mostly leaf, as well as lower fiber, and higher in sugars, fat, and protein. 1st cut is mostly stems, it's very crunchy with very little leaf, it's high in fiber and low in protein and fat making it great for tooth wear, but most chins wont eat it. The ideal hay for daily feeding is second cut, which is a nice mix of crunchy stems and soft tasty leaves. A lot of the bigger companies don't sell hay in specific cuts though, so most are a mix of whatever they have on hand when they are bagging up the hay, so earlier in the season it's going to be bags of mostly 1st cut, then mostly 2nd, then mostly 3rd.
