Consider ordering from Metzer (I like them a lot) or other hatcheries if you are able. They were good sexing the ducklings I ordered and even got the breeds I wanted instead of picking from a random box!
Do you know what the breeds you currently have are?
Hi there. :frow
I don't know anyone who trades drakes for hens. :hmm
Have you tried craigslist farm and garden or pet sections to offer your trade? :fl
