I have my 2 6+ week old EE chicks outside in an area separate from from my 9 month old pullets. The babies use a large igloo as their coop. Anyway, at bedtime they go up and down the ramp to their coop several times. Tonight I watched them for a while. When they come down the ramp after deciding it wasn't time for bed after all they stretch their necks and look all around as if to find a way out of the area I have confined them too. (The area they have is about 10 ft. x 5 ft.) Several times they flew up and landed on the plastic chicken "wire" I have used to separate the flock. They are loudly peeping like crazy all the time they are doing this. Finally they settle down and go up the ramp and into the igloo for the night. This ritual usually takes about 10 minutes. Is this normal?
