This one has always been my favourite, but I am concerned about the size of her huge legs. They are both 4 weeks old. She is the biggest chick, shy and gentle. She is also the only one that hasn't grown a tail. This chick was tagged at 2 weeks for being extremely aggressive on their first day out on grass. His comb looks a little pink already, he's displaying a lot of male behaviour and is very adventurous, but hasn't grown as big legs as the top one. His tail is also typical of all my other chicks. As they are 4 weeks old which may be a bit young, but I'm dying to know what gender they are so I can see how my guessing is going with the other 9. Also, does anyone know what the lack of tail at this age indicates?
