Is this a sign to cut the friendship off

My friend started acting weird. She keep making these zoophile jokes. Mostly about pigeons. She kept talking to me about pigeons like: "Hey,what if I finger a pigeon?" "I wonder where the hole is." "I wanna get pregnant and carry a pigeon's child. I wonder what the child will look like". At first it was funny bc she was telling me to imagine a pigeon with four legs and a tail but she started making it really uncomfortable. Is it a sign to cut if my friendship with her?
