Do i have to separate the new rooster, and it meeds to calm down a bit lol, he hasn't calmed down yet, since he has been moved here so it probably isn't him as he isn't really taking an interest in the girls at the minuteYep, they coud have been from both roos.
I have a slight concern though. What's your biosecurity like? It's recommended that you quarentine for at least two weeks to not transmit fatal disease into your flock.
You don't HAVE to separate him, but it's highly recommended. Check out this link to why you really really should quarantine.
