kikei growth on dendrobium

[marcey]

I'm really not sure what type of orchid this is. I think it might be a dendrobium. so, it's growing a kikei--baby. I think that's what it's called. What should I do with it? Should I remove it and plant it separately? I just want to make sure that I don't kill it. Also, reading about dendrobiums, should I not water it in the winter? Thank you in advance for your feedback.
