8 week old. 5 week old. 5 week old's face, 3 week old's tiny crest. 3 week old. This is Sunny, 3 weeks! The little family - 5 wk, and two 3 weeks. I bought 5 chicks from a breeder. They are now 8 wks, 5 wks, and 3 weeks old. Two of them are growing much faster than the 15 SFH I have raised and they are far more boisterous. I am confident the gray baby is SFH. I would love to get second opinions about all of them from the folks who know. Thank you for any help you can offer me.
