Your selection of channels are attached to your Roku ACCOUNT. Any Roku linked to that same Roku account will get the same group of channels, although they may load in a different order. Add/delete on one Roku, you add/delete on all.
Exception: If your Streaming Stick is an old model (model number below 3600) some channel apps that require the capabilities added in later models will not load or be shown in Roku home page menu item Streaming Channels. You can check your model number via Roku menu path Settings > System > About.
