Most likely not. They usually hatch day 17 or 18. Any that hatch day 21-22 are likely to be weaker.It is the hatch day that counts. You want them to hatch during a waxing moon, in the fruitful signs (the water signs) of Pisces, Cancer, or Scorpio. February 7th & 8th are the favorable hatch days for chicks so setting eggs on January 17-18th was the recommended timing. If you set yours late on the 19th, maybe you'll have at least a few hatch on the 7th.
For the February hatch I too set mine (chicken eggs though) on the 19th of Jan. however & I did include some shipped Svarthöna eggs in this batch and have never hatched shipped eggs let alone Svarthönas before so not sure if they will behave as my other chicks & hatch out a day early:/ hmmm...soon we shall see!
