my chickens are 7 1/2 weeks old. i think they're too young to go outside their coop because of my cats. right now there staying with my young ducks because my big chickens abuse them if they get their beaks on them. but i was filling a small tub for my ducks to swim in then the ducks got scared and started running around the pen. the chickens got scared of the ducks and they squeezed out of this teeny hole that i have since patched. but when they were out the cats were looking like "oh its just another dumb bird" but when they're in the coop there are 5 next to it stocking them
