My boy is 4 months old, he was born in town and never exposed to any other animals except dogs/cats. The first time he saw chickens he wanted to say hi but I made him leave them alone, it's been 2/3 weeks and he doesn't look at them.  He's very very ready to hang more with the goats,  he goes to the field with them when I let him and lays thete watching them but I just dont trust him long term alone yet.  He's shown some promise helping me gather goats,  I'm very excited for him to have it down. He's soooo good with babies too and doesn't even look at our free-range rabbits. I was given the dog for free! I still can't believe it
