I have a question about bigger cages and heat lamps

[WCReloaded]

My guineas are getting big and they can fly all over their cage. I would like to know what age I can start taking the heat lamp away and move them to a bigger cage cause the one they are in now is getting small fast.

How old are they now?
Are they Feathered?
What are your day & Night temps?

You can put them in a bigger cage now.

Just have the heat lamp at one end. They will go under it if they feel too cold.
