Hey Everyone! My call ducklings will be 3 weeks tomorrow. Anyone have any tips on telling male or female? I have 5 babies, I know one is a female for sure bc she is extremely loud! I noticed 2 of them seem slightly bigger, and their tail feathers are longer than the other 3. Any suggestions or pointers would be great! Hoping for more females than just one! I don't want to have to part with any of them. TIA!
