Silkie Hatching egg color question

[4chickns]

We had ordered silkie hatching eggs from The Garry Farm ( our first time with shipped eggs and using an incubator). Thanks to all the information provided by everyone on here we were able to educate ourselves before they arrived, and the hatch so far seems to be going very well. We are on day 10 and it looks like we have 11 out of 14 still developing. My question is about the colors marked on the shell. We have 2 that look like they are marked "hbsi" Does anyone know what that would mean?
Thank you!

I looked at their website, and I have no idea. Perhaps you can call or email them and ask?

Thanks, I did check their website and also emailed, I just haven't heard back yet. I'm sure they get pretty busy shipping all those eggs
