Someone had posted a thread about spraying them with ACV and then combining. I tried that, and for about 20 minutes I stayed out there watching, and sniper sprayed anyone who tried to cause issues, then I went back out once an hour for reminders, but after 2 hours no one needed reminding. I combined a group of about 6 week olds with 3 and 1/2 week olds 11 and 14 birds that had never seen each other before, and have had no issues. Theyāve been together over a week now with no problems. The extra boys are leaving this Saturday for a new home so I hope to maintain the peace until then.
