My 11 week dutch chicks have been outside a while now, but only in a proper coop and run for a week. Today is driving rain and pretty windy. Every night I gather them up and shut them in the coop and every morning when I open the door, they burst out into the run and start furiously scratching around in the grass (or whats left of it). They never go in the coop except when its dusk and I put them in, today they are huddled under the sheltered part of the run under the coop being blown around by the wind but still won't take shelter in the coop. Is this normal? This is my little coop.
