This is a great thread!
I let my chickens out in the afternoon when I am sure that I won't have to leave. They go to their coop for food and water periodically but otherwise they love hanging out under the bushes and trees in the yard. They are especially loving my raspberry patch right now! They go back to the coop on their own every evening around 8 pm.
My younger silkies and cochin also get to go out at the same time. They tend to stick together in their own little group and poke around. The "big girls" like to go visit their little pen and eat their food too. Sometimes my little cochin roo chases them away and sometimes he gets put in his place. Lol! I am hoping to be able to integrate them all together into the main coop eventually. Right now we are taking it slow and just letting them free range together. I do have to lead these little guys back to their pen most evenings.
Pretty quick here my Cornish X will be moving to the chicken tractor. I plan to give them an open door in the afternoon when everyone else free ranges too. I really look forward to seeing those fat little round chickens foraging around!
