Hi, this baby is about 4.5 weeks. I am not sure what breed he is, but based on his huge feet feathers and recent attitude, I am thinking he is a roo. He chases my hand when I am cleaning the food dishes, and jumps up my arm while Im in the brooder. He is not necessarily agressive to the other chicks, but I am wondering if he is roo just based on his HUGE feathers coming off his feet. He is def more "outgoing" than than the others....Can anyone tell what breed, and can you tell if this is a roo? I am thinking so... I also think he might be a Belgian Mille? He is a bantam, just not sure what kind.....help?
