Looks and sounds pretty good!
Is that picket fence on the property line?
Doesn't look like you have much room to get between picket fence and run wall.
That's a tough call.
I too started in the fall with an adult flock.
Eggs right off the bat was great!
The lice, scaly leg mites, and respiratory issues they brought with them was not so great and took a few years to get under control.
But I bought from a another backyarder, not a hatchery.
