Any idea where to buy some big, empty cable reels for goats?

How is everyone doing? So as you know, We’ve has some time on our hands and got around to building a goat barn for some sweet little Nigerian Dwarf goats and I’m looking for a couple good sized empty cable reels for the goats to lay on-anyone know where I can snag a couple? Swear I’ll post pics of the goats when we go to pick them up on Thursday! Thanks!
