My rescued Mallards were 3 weeks when I introduced them to a newly hatched Wood Duck. They were Not welcoming and chased and pecked at the tiny little guy. I acquired 2 newly hatched Muscovy to keep him company. I want all to get along so eventually they can roam freely. To this extent, I divided the large duck house (secured at night to keep predators out) into 2 parts separated with chicken wire. I had hopes that in keeping them together might force my Mallards to accept the younger ducklings. However, my mallards are just irritated by them and peck at wire when they get close. They also avoid retreating to the house just to rest or avoid weather, I have to bait then in with food at night. Is there any chance of friendship or at least civility between them?
