Welcome to Backyard Chickens! We are glad you joined the flock! BYC is a helpful site providing all of the information you need to know about poultry. There is always space for more members on the BYC roost! It sounds as if you are getting to a good start with chicken raising. A secure coop without holes reduces the risk of dead birds to quite a percentage. A limited amount of cockerels is also very important to reduce stress on the hens. Hope you enjoy it here as much as we all do!
