Hi i have 4 chickens. One is an Easter egger, blue sapphire, red sex link, and silkie. They are all hens for sure. They are now about 21 1/5 weeks old. They have a run. Have been on layer feed. Have two nesting boxes. Have a coop. But they haven’t laid a single egg. I’m worried I’m doing something wrong. I live near Salem, Oregon. The weather has been in the 40s with rain here and there. Thank you!!
