Got a Speckle Sussex and a Silver Ameraucana last week. Once a day I like to take them out of the brooder and place them in a 20 inch high enclosure on the lawn. The problem is that they have flown out of it twice. Did not have that problem with Buff Orpington’s. Are these two breeds flighty as chicks and is it a harbinger of adult problems which I should begin to work on, i.e., higher fences.
