You have a nice mix. Black Sex Links are my personal favorite. They are friendly and hardy, egg laying machines. I've raised them for years (along with dozens of other breeds) and they have been my best layers, consistently churning out more than 300 eggs per hen per year. You should get loads of eggs with that girl. With regard to a little diarrhea, if none of the chicks are not having any problems such as being huddled up in the corners, shivering, not eating well, or bloody watery diarrhea, I wouldn't be concerned about it. But I would keep an eye out for these type of symptoms as they are indicators of coccidiosis. If you notice these kind of symptoms, I would advise immediately posting on our Emergencies, Diseases, Injuries, or Cures section at https://www.backyardchickens.com/f/10/emergencies-diseases-injuries-and-cures. Good luck with your chicks.
