Wow! Welomme to BYC! You have such a great story. So you hatched out some mystery eggs and have a small flock of them? I can only offer a pdf file to breeds to hekp you to identify them, or would suggest you shoot us some pictures.. we do love those. Do you know much about their basic needs? I am only asking the questiona below as your into suggested they were a total unexpected experience. Chick starter heat and water are all they need. Also chick grit and a dustbuster with a one way seal is a great way to provide them with bugs as I do for my new starts!
1-please have chick starter on hand to feed them
2-they need warmth around 90F for the first week
3- duh water.
