I bought 8 ducklings from the assorted lot and I'm curious what exactly they all all. I'm pretty sure the HUGE yellow white one is a Pekin. The black ones maybe runners? But the two grays and brown red one I have no idea. They're about 7-8 weeks? Warning: they are super dirty because they make a huge mess with their food and get it on each other and pool is messy for same reason.
