My 24 week old Silkie, Bess, just laid her first egg. I was so excited. It is the cutest thing. Next day she laid another one. Don't know if they are fertile. I do have a Silkie Rooster. Think I'll wait until spring to let her sit on any. The chicks must be so small. Anyone raised baby Silkies? How small are they. Mine were 2 days old and normal size chicks. Do the eggs get bigger as they get older?
Generally, a pullet's eggs get slightly bigger (and more uniform and refined) as she gets older. They don't change a lot, though.
