Need help! Husband and I introduced our 5 week old ducks to the flock we have. We have 1 drake and 2 ducks in the coop. As soon as we put the newbies in there, the drake started tearing them up and being really aggressive, it looked like the girls were trying to stop him. Is this normal behavior for a drake?? We thought maybe one or both of the younger ducks may be drakes and the older one doesn't want him/them. My husband got one out quickly and the other was able to escape thru a small hole. Both unharmed. How do we transition the flocks together?? Also, I'm letting the girls keep their eggs instead of collecting them but they are not nesting yet, still getting them built up.
