It is so exciting and fun to hatch chick's. I can't wait for our second batch to start hatching. At only 11 day's old I noticed that they started to get feathers on there wing's. I check on them often but they let me know if something is wrong, such as if there food dish goes empty or if there light goes out. They start peeping repeatedly. They are 2 week's old know and are very playfull. The first week of there life I found them to be very loving. They are very courious to say the least alway's streaching there necks out to have a look around.
