If you put something between the pens that blocks sight (like several people have suggested), that will probably block wind too. So you might not have to do anything special for the winter.Ugh, I just remembered, I planned on wrapping the backside of the girls' pen with a thick clear tarp as a wind block during winter and take it down in spring. But, the roos will be on that backside, so now I don't know how I'm supposed to wrap their pen and be able to take it down without going in the roosters pen. I'd put the roosters on a different side of the hens' pen, but it's already fenced off for our ducks.
If you really need to do something in the rooster pen, plan a day in advance and you can probably avoid most problems: after dark, grab the roosters and put them in something like a dog crate. Let them sleep in the dog crate, do your job in the morning, and then let the roosters back into their usual pen.
Chickens don't see well in the dark, and are usually sleepy. So you should be able to grab them without being attacked, although when you do pick them up they might flap their wings a bit and possibly try to bite you (solution: thick coat, maybe gloves. You won't need to wear the protection for long, if you are just stuffing the roosters into a crate and then leaving them for the night.)
