I have an older male duck thats almost a year, he was paired with another male duck so they werent lonely. One of my ducks was killed so now my duck Melman is by himself. We bought 4 other ducklings so he could have amore friends. The first two are arpund 4 and 5 weeks and the second batch is 3 weeks. One of the ducks in the second batch was injured by his friends stepping on him so nos his growth had slowed compared to the others and is small compared to the 5 week old duckling. I want to know if its his injurt thats caused his growth to slow. My second issue is that my oldest duck Melman has been pecking at them quite harshly and ingured the amallest duck so now hes hurt again. They are seperated by a cage. The side of the cage were both the duck and ducklings meet i put a lid to a container to block Melman from pecking them but there is a small gap where he can see the ducklinfs so they can slowly get used to each other. Well i was in bed and i looked over and Melman was picking at the smallest one theough that small opening (therea still the cage between them just not a barrier). Is this behavior goinf to go away when they get bigger. I took the smallest out the cage and hes in my lap so he cant get bullued but my other ducklings are in the cage near Melman and he keeps quaking at them and tries to stick his head through the gap but they keep away anytime he gets close to them. What ahould i do???
