Hi! First post! I have one standard and four bantam hens about three years old in outside run with coop. Got six one week old standard baby chicks two weeks ago. They are growing big quickly in pen in our basement (with heat lamp) until ready to go outside. Live in NC. Temps are 80 during days. Low 70s/High 60s at night. Was planning on six weeks but also wanted to introduce to bantams when similar size to avoid too much conflict with pecking order. Not sure how to determine exactly when ready...i.e. "feathered." Also, plan to put in separate pen inside run for week or so to acclimate. I am worried about transition timing and process. Very nervous! Don't want to mess up existing ones or new ones. Any input is appreciated!
