Coons do come out during daylight hours. I had one kill a bunch of ducks after 8:00 and shortly thereafter I seen a whole coon family out and about at 9:52 a.m. If you catch and release, you have just made a trap-wise coon that can be almost impossible to catch in a hav-a-hart trap. I've tried everything. Now someone recommended an egg-trap. I googled it and am going to get a few. Theory on it is sound.
