Black goat and yellow in white goat.

I keep two goats at home, one black and one yellow in white.

My two goats are about 2 years old, I keep them since they were 2 weeks old ..

a black goat is one of the goats that I have to watch every time so that he does not go astray into the middle of the forest, I do it because the scapegoat I have very rarely issued a voice despite having been called repeatedly....

while the yellow-white ones include goats that have a rough and tall voice, although he goes into the middle of the forest will be very easy to find because he immediately answered when called, not as black.

thank you,..
