So I have 4 week old chicks. Had them for 3 weeks now, and yes my first time. My husband is currently building a 10' x 10' run for them (and 2 -4 month old ducks I have). We also just got a nice chicken coop so they can hang outside while the large pen is being built. So today is the first day they are outside. I put them all inside their house, and slowly watched them go outside, figuring out the ramp. I am home now for lunch, had to go outside to check them out and they are still outside. I put one back in the house and she slid down the ramp. My question, do they know to climb the ramp to go back inside tonight? Or do I have to put them in there and lock them in there which I really don't want to do. And today would be early like 5 PM cause I won't be home tonight .
