Can't get ducks in their pen

[bigbird]

I have seven ducks that are pen trained. Every night, they wait for their buckets of veggies and fruits, and go right on their pen.
I had a weassle hanging around, and eventually an attack on two of my chickens in the night. Now, they don't want to go in. It's taking me hours ,and four people to chase,and make them go in.
Any ideas?
I reinforced their pen with more hard cloth, and I know they don'tikd change, but they are driving me crazy.

I "funnel" my ducks into their pens by walking behind them into a corridor of wire puppy pens on either side, like Native Americans used to correl their game. Make sure you have treats for them.

I do have treats. That's how I get them in every night. I have all in but two, and can't get them off the pond.
