Hi! I need advice on integrating 12 chicks into my flock of 8 pullets. The chicks are 4 weeks old and fully feathered and off of heat in the garage. The pullets are 12 weeks old. I have the chicks in a grow out pen that I plan to move to either the coop or the run. Which is the better option? Both are predator proofed and have sand floor. The coop has ventilation and cool during the day but I can't easily see the chicks without going in the coop; whereas the run is fully visible and has lighting at night too for me to monitor. I just worry if I put them in the run in the brooder box then when its time to fully integrate they won't want to go into the coop. Any advice welcome!
