Distance restrictions between the location of the chicken coop and property lines, or coop
and nearby residences, were stated in 16 of the ordinances evaluated. There were no
restrictions in 3 of the ordinances and 5 were unclear. Of the 16 with distance
restrictions, 12 were distances required from residences, while 3 were distances required
from property lines. The distance required from property lines ranged from 10 to 90 feet,
while the distances from residences ranged from 20 to 50 feet.

To summarize: the authors looked at 25 cities that allowed chickens. Five were unclear about setbacks from the property line. That leaves 20. There were no restrictions in three. That leaves 17, although the report only refers to 16. Of the 16 only three required setbacks from the property line. Those three varied widely -- 10 feet, 25 feet and 90 feet. Clearly 90 feet is an anomalous outlier. The fact is the most common setback for the coop from the property line is zero feet.
CLUCK is going along with 10 feet, even though the mobility of the Sarasota coops will allow distances to be adjusted "on the fly". Since the coops can be moved, there is no need to obsess about distances when they are not fixed.
As for distances from residences, chicken opponents should argue for coops closer to the owner's own residences so that they might be aware of any problems.
