I can also recommend the 'mixed mutts' as I've had success there, a friend gave me some eggs to 'test' his rooster is doing it's job and I got 6 out of maybe 7 that hatched and seem very healthy in their 2nd week. Also, my first ever hatched out chicks, a pair of girls, are very very sweet and quiet and calm and lay eggs very well. You can expect whatever you raise yourself to be calm and quiet and that they'll like you.
Btw, my polish recommendation, for people who were not following the thread is in addition to nugget's 6 existing chooks, so laying is not relevant. Looks are worth it alone.
Well, she did say she wanted some "good layers" so I assumed laying was relevant.
