Blue roses are really, really hard to breed. When I started breeding them, it took me a while to get them too.
My advice for you is to make sure you know which of your reds are the hybrids, and set them aside so you don't get them mixed up with regular reds. I moved my hybrid reds and I was able to get blue from them, so I don't think picking them up resets them. Also, if you still can't breed them for some reason, you could always buy a couple blue roses from someone on the forums, and just make more blues from those.
I hope this helps! Good luck!
