I have had the same issue with Small Pet Select but only with their 3rd cut Timothy. The second cut was so hard it seems like a 1st cut so my buns wouldn’t eat it but it did have such a nice color and length. The Orchard Hay in my sample box was also really nice and I was hoping my bunnies would like it but unfortunately they didn’t like that either.
I bought a big box of the 3rd cut with the hopes that it would have more longer strands than the sample box I bought but it’s mostly short like you described and the box is full of dust. My bunnies like the hay but it’s a mess. The other day I went through and tried to shake out most of the dust and shortest strands and l ended up throwing away a lot of hay.
I contacted SPS a while back and they did confirm that the strand length can vary batch to batch. They had me email a picture of the hay I received so they could forward the information. They were really nice about giving me a credit since my bunnies wouldn’t eat the 2nd cut. Even with their good service I am going to go back to Farmer Dave’s. Their 2nd cut has always been really nice and long if you are looking for a softer Timothy …although a little on the pricey side. I don’t want to keep getting so much hay that is unusable.
I know a lot of people are happy with Oxbow and Small Pet Select though. The other recommendation I see a lot is finding a local farmer that sells grass hay for horses also. This is definitely a cheaper route but I haven’t been comfortable doing it yet.
