Yep, if you look around on Ideals website (I believe on the page where they have the shipping info) they do state that they'll send extra males for warmth. We eat our extra cockerel, so I've never minded them, but I normally order at least 25 chicks, so I don't get them very often. Reaching out to reptile owners is a fantastic idea though!
Good luck finding a use for them!
