We have 13 total. 1 rooster (15 weeks) and 12 hens. 6 are 8 weeks old and 7 are 15. The younger ones have been in a dog kennel inside of the main coop for about 3 to 4 weeks now. All 13 have been separated so far but I'm wondering if it's almost time to let them loose with the older ones. Thinking I can fashion the kennel to have big enough openings for the little ones to escape through into the safety of the kennel. Any tips are welcome. Thank you in advance.
