“Animal Names: Minhag is to name “Chayos” which the shvatim were compared to. We don’t name after “b’haimos” even kosher ones”.
Wrong. What about Shepsel for one.
Also, there were g’dolim such as Rav Ruderman who had einicklech with the name Shira. And what about the custom of naming females from words in p’sukim of Shir Hashirim?
