I pinion our chicks while they're young because catching them when they're older is more difficult. We tried clipping their wings & later they'd fly over the fence into our neighbor's yard. Now they have 5 Great Danes that have the run of their fenced property & I pinion our chicks to prevent them from becoming dogfood. We have 5 roosters with 2 of them with the hens & the others guarding the perimeter Plus a spayed Lab to spread her scent around as another precaution plus she spooked a raccoon so badly that it didn't think to grab a chicken to go.
