Hens second sitting

[zadok]

This is the second time for the hen to become broody. Will they look like the first hatching?. Will juvenile roosters continue to get along with mature rooster or will I have to sell or separate? Thanks

If the chicks have the same parents, then they will probably look similar. Some parents are able to produce chicks with many different colors/patterns, in which case you may get some that look different than the first batch.

Will juvenile roosters continue to get along with mature rooster or will I have to sell or separate?

At some point, all the juvenile roosters will have grown into mature roosters. They will probably not get along well at that point.
Things that could change the situation:
--if they have LOTS of space, they may be fine forever. (By LOTS of space, I mean several acres of land all day, every day.)
--certain breeds would certainly not get along: gamefowl (used for cockfighting) being the obvious example of ones that would not live peacefully together.
--males are more likely to get along if there are no females in the pen. So having one large pen for males, and a different large pen for females, might be a solution.
--you mention selling or separating. Some people consider eating to be another solution. All chickens are edible, even if they are not "meat" breeds. (I know it's not for everyone, so please don't feel pushed to do anything you're not comfortable with.)
