This is what happened to me too.
It was my second net from them. The first one I had for a couple of years and it had what I felt was a reasonable amount of holes, but I wanted a new one.
I ordered, got it. Put it out and literally was immediately patching holes.
Everyday, more holes.
When I contacted Hay Chix I was told that it must be my horses destroying it, not their net being faulty.
I explained that it was not my first net from them and these horses eat out of small hole hay nets in their stalls (smaller holes) with no issue, that I felt this net must be defective material, not their fault, but the fault of who they bought the netting from, but it did not seem right that my brand new net was full of patches already.
They demanded I send photo of the holes. Not sure what that shows, but I sent photos and they just continued to insist it was my horses fault.
That is the only net I have ever had that much trouble with, ever. (18 years of feeding in nets.) But after that experience I was certainly not going to buy another from them.
