I just finished my new coop that is 10 by 8 and has a 6 by 8 run. It is totally secure. I just put my silkies in there today and life is good!! Everything is perfect; my coop is perfect, my chicks are healthy, and it is almost friday!! I will soon by posting pics of my almost three week old silkies. I put them outside with no drafts and a 250 watt light bulb. People say only put chicks outside when they are atleast six weeks. I have been hatching chicks and put them outside with a heat lamp as soon as they were born and they had no problems. Should I not be putting them outside at this age? I mean, its the same temp in the coop than it is inside. Ohhh and I am from SOUTHERN louisiana so it is pretty hot!! But, life is perfect especially with silkie chicks!!!!!
