I want to separate my tulip bulbs

Question

I want to separate my tulip bulbs. However, I moved to my new residence last fall. I was told that there were tulips here but couldn’t be given an exact placement. They have started growth, so I found them, but they are way over crowded and need to be separated. Is it too late to separate since they have sprouted? Should I wait until after bloom is finished?
