How long does it take for a convict to get a hump on its head?

[JustinCase]

I really love they way they look and I'm wondering if anyone knows around how long they take to develop

It really is based on genetics, so it's almost impossible to say. But as I have only ever seen defined ones on older males, I'd say a year +.

I hope so I found this picture on some forum with a beautiful convict

Mine is about six months and has one but is fed very well which might have helped him grow quicker

Mine is probably about 5 months and doesn't have one
