My ray is giving birth tonight as I type this. One pup is out and seems fine but the next one appears to be having trouble. It's tail is out but has been like that for at least one hour perhaps longer. Does anyone know if it's normal for rays to be born tail first? I'd like to be able to help but I'm afraid I would stress mom too much so I'm letting them be. I'm concerned about the pup being stillborn as well as concerned about the moms health. Any advice from ray breeders out there?
