My chickens are currently living in my spare bedroom as we build their coops. They turned 19 weeks old today and I have been expecting eggs any day now. Their sister ducklets are now hens as they laid their first eggs yesterday. Will my pullets lay without a nesting box? Should I go ahead and add one in their temporary home? They will have their new home by Sunday but I am worried I am stunting their production or something... I may just be worrying too much!
