The chicks stayed out happily in their tractor for 21/2 hours or so. They would have stayed out longer, but when I went our to check on them 2 of the 3 tractors had been knocked over by the wind! Needless to say, I freaked out. Their tractor was the only one that stayed upright, thank God! I had my sister put them back into the brooder while I chased down the three fighting bantam roosters. -_- They get along fine as long as "FeatherFeet" (the one we are going to eat) stays in his tractor. But, of course, with it being knocked over, he didn't. Grr. Why can't they get along?
