I have looked all over the site and have found many different answers to my question. so here are my specifics........ I have 21 chicks that are around 2 1/2 weeks old. They are currently in a brooder in our garage with a light at about 80 degrees. They spend ALL day out in a small fenced area of their larger run, 18' x 30', but right now do not have access to the coop just food and water. They spend all day being chickens. Our weather has been in the high 80's during the day and in the 70's at night. Should I go ahead and move them out to the coop with a light? Here is the coop and run.. not covered in this photo but covered now And here is a pic of one of my babies showing how feathered she is...... I know most say to wait til they are fully feathered but they seem so happy outside....... any thoughts?
