Hi all very interesting post! I am new to roosters as well. I have two brothers that are almost 16 weeks that I hatched (first time). I know how you can get attached to a chick when you raise it.
The youngest, but larger, brother Ewok is showing some "cocky" behavior. He used to be so friendly even jumping in your lap. Now fluffing, sides steps, and two mock charges at me. As well as some aggression towards the hens, even mating behavior. In fact the other day I saw him mount his sister. Now Jet on the hand is a scardey rooster with me and the larger hens. I cant get within 5 feet without him taking off. He has shown no signs of aggression.
I am keeping Jet. His coloring and body type is more what I'm looking for anyway. I also read that you want a rooster that is more timid. Roos that super friendly, and are not the least bit afraid of you, are more likely to challenge you because they are not afraid to try.
I was going to wait until I rehomed Ewok. I say 80% of the time he is a great bird. After reading this post however I'm thinking sooner so his new owners can work with him. I would say the freezer but just did a bunch of CX and freezer camp is full. Plus 20 CX and no plucker, eesh done for a while.
I am loving how every one has their own opinion on what to do with trouble roos. I guess its the 3 R's Rehabilitate, Rehome or Rotisserie.
Take care.....
