i sectioned off a corner of my coop for my 17 chicks. i wont be bringing them home for about 3 more weeks. but my big flock are roosting on the top railing of the new section i made it 6ft long by 4ft wide. for17 chicks at 6 weeks probably too small. i also have a 12x12 outside pen i could put them in. would they be alright outside at 6 weeks old. i will have to build them a house to go in at night if i do the 12x12 outside pen. any info thanks.
