Hi there! I'm new to this, so bear with me. 3 years ago, we got a week old pekin duck (Frank) and when he was about 4 months old, we rescued a khaki Campbell companion for him of around the same age (Charlie). We were told he was a female but he turned out to be male. Frank and Charlie bonded and everything worked out well (although they would take turns "mating" with each other on occasion). About 3 weeks ago, however, Charlie passed away unexpectedly. Frank was absolutely destroyed. He wouldn't make any noise or eat or drink, so we rescued a year old female blue swede (Sweet Dee) for him. They bonded immediately and Frank has become aggressive in protection of her (he chases the dogs and tries to attack them when they get close to her). All seems to be going well but there has been no mating. So my question is....when will they mate? And outside of that, when will she start laying eggs (if ever). I should add, she is most definitely a female. Charlie didn't have his drake feather when we got him, which is why we were uncertain. Any insight is very appreciated!
