I recently received 8 chicks,all different breeds from a mail order. They are now 3.5 weeks old. One is an Easter Egger and she is the slowest to develop.I know all breeds develop differently and have different features. But I'm starting to wonder whether she really is a she for some reason. She is also the most shy out of all chicks. Also has a ton of toes! I am new to this...I've included a few photos..I appreciate any insight!
