Hello! I've had my 5 baby chicks for two weeks. I started them in a large tote which I slid into my extra large dog kennel to keep them safe from my two cats and two dogs. This worked extremely well...until Friday when they started to fly! They seemed too big to fit through the bars of the kennel, so I wasn't too worried. However, one managed to escape! So, I had to cover the entire dog cage in wire! Since theyhave double in size, I decided to remove the tote and just let them run around the cage. They love the extra room...BUT now seem to be fighting a lot and doing this thing where they stretch up real tall, flap their wings and "chest bump". Are they already trying to establish a pecking order? or do I need to be concerned about them not getting along?
