Hi, i'm new here, but i've had chickens for a long time. I have a young rooster, who has always been really cute and friendly. He always followed me when he saw me, and was incredibly easy to catch, as he didn't run away. Recently however, he has grown up quite a bit (he's still very small though), and will always run off when i approach him to get him into his little "home" (i have no idea of the names in english, sorry). Is there any "tips and tricks" to make him friendly and docile again? I've been worried that he might have had some traumatic experiences with my cousins maybe, or with some predator. No idea. Thats why i'm asking 
Thanks in advance!

Thanks in advance!
