My husband is demanding plans for grow out pens for silkies to put in our garage. He wants them off the ground because he thinks that it will be too cold on ground level for them. We want to use as few heat lamps as possible. I want them as big as possible but still be able to reach to clean them without crawling inside of them. So I guess I am looking for pictures of grow out pens that are elevated or on tables and wondering as to how many inches tall they need to be so the silkies don't jump out. They will stay there until they are feathered enough to go in the outside coop. I figure I would need to house around 24 chicks. Any ideas would be greatly appreciated. Thanks
