On Christmas morning my husband gave me something I'd wanted a long time: my very first chicken coop. Inside were two sweet red hens, gifts from a daughter. The latches on the coop are flimsy, absolutely worthless. We went to HD to get some that will protect the girls, but left very confused. Would you mind telling this newbie what kind works best (in your experienced opinions) to keep predators out of a coop? Thank you!
