I have 2 6 week old Americanas that I hatched. I have placed them in a large dog crate within my chicken run (no room in coop for crate). I have placed a75 watt light that goes on in the evening to give them a little warmth. they have plenty of food and water. They are in the shady part of the run. Is this ok for a couple more weeks. I am planning on partitioning off a 6 foot area of the run and build a small box for them to go into in the evening, but I won't have time to do this for another 2 weeks. I thought it would be better for them in the run so they get a bit of fresh air then being kept in the garage.
