This question is for anyone that has experience with Cayugas or Black East Indies. I'm considering getting either a pair of Black East Indies or one Cayuga hen to go with my flock of Welsh Harlequins. I'm interested in the egg color. While the two breeds are similar I want to know their differences. I assume the main one is size. How big is the size difference? What about their personalities? Who is louder? Who is friendlier? Do they both have the same level of tameness? How many eggs can you expect to get each year? Do they both get white feathers as they age? Will a Black East Indie drake try to mate with the Welsh Harlequins? Will he be successful? Can Black East Indies be kept with call ducks? If you had a choice which one would you get?
