Hi I have 2 Cayuge ducks - a male and female - that I've had for 8 years and tragically the duck was killed by something today - possibly a dog - and the drake is now all alone (apart from the hens who he doesn't get on with) I intend to find him some friends/mates but would like advice on whether you can mix duck breeds, if Im not able to find any more Cayuges. He's not the friendliest of drakes and is a bit of as grumpy old man now, but I can't leave him by himself. I know I'd have to go for larger size ducks due to his size. What do people think - will it work?
