I’ve read through this whole thread, and I really didn’t see anything that was insulting. I saw things that you certainly did not like, but it was pretty clear to an outsider that the poster was still trying to help your chickens and their cousins. As in, it looked to me like everything you received was a serious response to your question or the situation you described. I looked at your profile and saw this was your first thread in about a year. Perhaps you’re just more used to a different posting culture if you tend to use different sites and social media?
Anyway, I’m still in the process of integrating youngsters. We got them at 4 weeks, quarantined them in our house until they were 6.5 weeks, had to set up an internal fence in the run to give them a space to eat and drink without being persecuted by my hens until they were 10.5 weeks old and were getting too big to slip through the little doorways, and now they’re 13 weeks old. Only in the past week and a half have we been able to see small progress like my hens not taking EVERY opportunity to chase the littles away from wherever they were hanging out. It’s been a slow process. I would expect a very similar situation if I tried to integrate adults as is happening while integrating teenagers. Universally, the whole thing is way easier the more space the chickens have. People with big lots that can introduce their two flocks while everyone is free ranging seem to have the quickest turnaround time on this process. My coop and run are designed to house eight chickens with 4 ft^2 per chicken in the coop and 10 ft^2 per chicken in the run, and the whole thing still feels very cramped for just five chickens to be meeting each other. Everything is much better whenever we let them outside into the yard for supervised free ranging, even if the hens are still trying to assert their dominance every once in a while. I do not know why things went so easily for you last summer. Perhaps they still remembered each other then but don’t now.
