Introducing (2) 7 week old chicks to (2) more 7 week old chicks

[LLL]

Hi, I've received some wonderful advice regarding my knowledge around the "pecking order". We've made the decision to rehome our 1 older EE and one young adult RIR. We will then start over with our (2) 7 week old ISA Brown chicks. It was suggested if I wanted more chickens to add more the same age which I think is a great idea. Before I get in over my head (again), I would like some feedback on anyone's experience regarding adding 2 more ISA Brown chicks the same age making a total of 4. Would bringing the 2 we have currently together with 2 strangers cause problems even though they are the same age and breed? I'll just stay with the 2 if they are going to peck at each other. Your feedback is appreciated and thank you!!!

I just put together 2 groups of 10 12week old chicks together and there were no issues at all.
One thing is to make sure there's enough room wherever you're housing them as I noticed chicks can get pretty mean to each other if they feel cramped. I had to leave them in their smaller brooders for a few extra days due to an issue, and in that time they bloodied eachother's tails pretty bad. Now that they're in appropriate sized housing, everything went smoothly and perfectly

Thank you -- we just built a very large run, so space is not an issue.
