I have 4 hens. Of the 4, only 1 is laying. She was born on April 1st 2012 and is a silkie. I have a bantam cochin who was born in April also and hasn't ever laid an egg. I have a standard cochin and another silkie-both born early summer and nothing from either of them. If they were born at a time of year which they'd come into lay in winter-would they just wait until spring instead?
