Things I wish I'd known and a few things I'm glad I did.
1. Build a "hen house" not a "coop" in other words, if you can,
build something large enough for a human size door, or else it can be very hard to clean.
2 Make sure you human doors swing out, not in.
3, Use PDZ and diamateous earth for chicken poop smells.
4. Put nest doors on the outside too, easy to get eggs.
5. Hang feeders/waterers close to the door inside.
6. Put a small waterer outside, under a little covered chicken shade area.
7. VENTILATION IS IMPORTANT. We put a 36" x 48" window on each side of the hen house, for cross ventilation. They have screens but we screwed hardward cloth over the entire window for extra security.
8. Make it your nightly ritual to say "good night boys and girls" and
close those run doors.
9. We put up electric poultry fencing and no problem with 4 legged predators. A little Brittany decided she wanted a chicken but quickly changed her mind after one bump of the fence.
10. We just put a $15.00 box fan from Wal Mart in one of the windows, and use it to pull stale air out and fresh air in. THIS WORKS REALLY WELL.
11. If at all possible, have electricity to the hen house.
12 If at all possible, put it on skids, so you can pull it around and change grazing areas.
By all means, haven't listed everything but I hope this helps or gives ideas to folks.
