In our pen we have 3 hens and a drake, They have a 30 gal black water trough as their "pond" , I free feed and they have a really large ex dog house as their coop. The pen is almost 8 ft wide and about 20 ft long, with 4 ft high sides. Here is the issue, every morning when I go out to check food and water, I find two hens next door at the neighbors. The drake and one hen will be in the coop looking at me calming but the other two are camped out at the neighbors house. They have done this so often all I have to do is open gates and they waddle back to our yard like a parade and straight back to the gate of their area. The minute they are inside the pen, the drake gives them verbal heck and they spend the rest of the day in the back corner of the pen. My question is this: Are Muscovys like geese and pair off for life? Or do they rotate partners? Do I need to separate my two hens from the love birds or is my Drake just being a jerk?
