Yes! The new and old chicks all put themselves into the coop tonight!

After the sun went down, I went to turn on the coop light and put in the chickens. The older ones around 3 months have just started to go in themselves but tonight the 2.5 week old chicks were in too. One of the chicks was actually roosting with the older bunch.

Keep checking on them at night - just incase one decides to stay up late and then cannot find the coop.

I know it's kinda silly, but I actually felt like I accomplished something when ours all returned on their own after a couple of nights. Like I was the great and powerful director of young chicken minds.
