What should I know when buying and freezing multiple rotisserie chickens?

I have lots of room in main and auxiliary mini freezers.

I would like to know how long that they can store in their original container in the freezer?
Or should I carve them up into segments and then freeze?
What packaging should I use to store them; or can they store in the plastic dome that they come in?

I live alone and I wonder how many a week can I eat before getting sick of them?

I prefer dark meat. Would it be better to buy whole rotisserie chickens or chicken wings and quarters?
All meat is getting pricey from inflation.
What are some alternatives from buying meat?
I don’t like sirloin, and I can eat fish.
