I had a Cayuga pair and the hen laid quite well. Both of them were very quiet and quite friendly, but the drake was friendlier. He loves me. He's now a widower; after his wife had been laying and walking away from her eggs for over a year, she started setting in a hap-hazard manner. Then she went broody on a secret stash of eggs in the front yard (including some from the chickens!), but after four days a predator got her. Now Louie is even more affectionate, without Thelma to care for/about.
I hatched 3 call ducklings and recently bought some Cayuga ducklings; they're about four weeks apart in age. The calls are outside in a grow-out pen and duck house; Louie is very interested in them but he went to nip the ducklings when I held one out to him. The Cayuga ducklings are still in the brooder in the house... I'm hoping to raise up a new wife for Louie and have a flock for him to rule.
Calls are adorable because of their small size, but they are very noisy - especially the girls. Thelma spoiled me, because she was so quiet. Maybe quacked about 10 times in 18 months. The rest of the time, she and Louie just gabbled to each other.
I highly recommend Cayugas. My experience has been wonderful (except for the predator getting Thelma, that is). I loved her eggs!
