Introducing my 9 week old chicks to the flock; can or should I attempt the integration? The background: I have 28, 9 week old chicks, 24 hens / 4 roosters, living in a 12x6 enclosed trailer brooder. I feed them chick-starter and every snack I can find, only healthy foods. My older flock is 4 RIR hens (all 1 year old), 1 Ameraucana hen, and 1 Ameraucana rooster (both 8 months old). The 4 RIR hens are truly “mean girls”; they fought the Ameraucana’s for weeks when I introduced them to my RIR hens. My RIR’s are so big and so spoiled that I don’t see how the new chicks would have a chance of surviving. The coop is 500sq ft, I open the back door before the sun rises and they have 2 archers to free range. I can wait until the chicks reach 16 weeks, but I’m changing their bedding weekly, which would be crazy if I have to wait 16 weeks. I’m really in over my head and could use any advice with this integration. Thank you for your time.
