I have 15 chicks on order of various breeds. Some such as the leghorns are listed as very wild and flighty. I have a large 200 sq foot coop / run but want to let the birds out during the day to forage. However, I am concerned that they may not return to the coop/ run so I can close it for the night for predator protection. Anyone got advice on how to ensure I can get flighty breeds of chickens back into the safety of the coop ?
