I had 6 young chickens approx 13 weeks old, i had to rehome 4 due to them all being roos. I have one roo and one pullet. The new chicks are roughly the same age, are there any rules to integrating them to the 2 that I currently have? Thinking due to age it shouldn’t be too big of a problem. I do plan to quarantine them for a week or two first. TYVM!
