I have 1 rooster and 5 chickens. Two days ago I noticed an eagle over my house. Three of my chickens disappeared. These 3 have often wandered off to lay eggs, which we find quickly! One chicken came back but the other 2 are still gone. I have read that they will go and lay eggs and 21 days later bring baby chicks back to the coop. I'm worried because it's cold out! A late frost here in Wa. I'm worried that the other chickens will attack the babies plus the big worry is, where are they! The rooster is calling but doesn't seem too worried. We did lose a chicken to something a month ago and all the chickens were freaking out! Where do I look? And if I find a nest, what do I do? Is it possible the chickens are close? We have a coop and lock them up at night but they free range on our wooded property.
