So I recently bought two pekin ducklings from Tractor Supply along with some pullets since I'm doing a pretty big expansion into my chicken coop! I have been told by many chicken and duck owners that the two can coexist without issues, but tonight I read a post where drakes were raping and killing hens? By the time my ducklings go outside I will have a total of 16 chickens (15 hens 1 rooster). Should I be concerned? Will have 3-4 female ducks with one drake make it safe for my chickens? If so I will more than likely order female ducklings which is why I wanted to know if anyone has had experience with the McMurray Hatchery?
