Put them in the coop after dark, night after night.So, how would you suggest I break them from perching on the roof?
Maybe in the big coop.
How long have birds been mingling?
Is big coop big enough for all birds?
Separate roost for newbies a good idea
Rig something on top of coop to deter perching there.
Is that ridge cap wood?
If so. I would drive some long screws at the ends and string some wire or string between them about 3" above ridge.
Might be good to start new thread so as not to continue to hijack this one.
