Hi all! I am new to the whole chicken raising, I just picked up my first pullets today! My flock consists of a Buff Orpington, RIR, Americana, and a Barred Rock. The guy I got my pullets from recommended that I keep my pullets cooped for 4-6 weeks. That seems incredibly long to me! They have a fenced run and access to the coop from the run. Should I wait the 4-6 weeks and leave them strictly in the coop or leave them in the coop for a few days and then let them out into the pen? I understand that since they are younger birds they are more susceptible to illnesses and moisture changes. I am feeding them a grower feed, grit, and water with a citric acid supplement (seller recommended for stressful times?) Just looking for some feedback and guidance from the more experienced chicken keepers! Thank you!
