Is the broody raising her chicks with the flock or separately?
Had my broody behind a wire wall splitting the coop until chicks were 2 weeks then took wall down.
Broody got into a few fights because she used to be a low hen and would no longer 'submit' to her 'superiors'.
3 pretty bad fights in the first 2 days that I had to break up because the rooster couldn't, but after that things were fine...chicks were never threatened.
When the cockerels hit about 13 weeks, there was some trouble,
mostly the main roo being to harder on his hens(competition) but also the cockerels gong after the pullets and the hens beating the cockerels up,
so I removed the cockerels, they were delicious.
Only time will tell what your birds will do if your possible a cockerel hits his hormones, your cock might keep thing in line or he may not.
Always best to have a wire dog crate or two around to isolate problem birds.
