I bought three hens and a huge rooster at a town auction, they said they were 7 months old. I've had them three weeks now and they haven't laid any eggs. I think they are maybe too old to lay❓ They are not very active, and one of them has a shut eye! How can you tell how old they are? I was afraid of getting baby chicks. I really don't know why. I'm thinking now, I will order some babies. Can anyone suggest a good hatchery?
