I don't remember how old they are off the top of my head, but they should be old enough to lay. I've built them a coop, they have a secure yard, and they have fresh food and water at all times. I let them out in the yard when the dogs are put inside so they can hunt for bugs and eat grass and seeds. My problem is is that they have not laid a single egg. There's four of them, and I'm concerned it may be the dogs scaring them. Does anyone have experience with their dogs harassing their chickens? If so, what did you do to keep the dogs away from them? My dogs have turned into complete asshats. The chickens are kept in a corner of the yard the dogs NEVER went into before, but since I've had the birds, they rub themselves on the fence, sit there and stare at them, and even play right in front of them. Besides putting a fence around the chicken fence, to keep the dogs out of that corner of the yard, I have no idea what to do.
