just added 2 new ducks to the pen today. I already had a male and female pekin raised together from ducklings about 1 1/2 yrs. old. the new ducks are about 4 months old, a female pekin she's just as big as my male and a female mallard. so 4 all together. now I was worried the older ducks would be the meanies due to age and it's there pen. boy I was wrong! the new pekin is very protective of the mallard they were raised together.they both have my original ducks scared (chasing them away and grabbing them if they come to close) will they work this out? I was hoping to give the new ducks a good home. they've been together now about 5 hrs. any ideas?
