I have 2 goats, 1 is female and the other is male. I got them when they were around 3 months old. I have had the boy neutered after 2 different surgeries. But they are very happy and healthy, but here lately I have noticed them eating plastic on the pine shavings bags I have for the chicken coops. Is this a bad thing or will this bother them? Apparently they haven't just started so I am guessing this won't bother them. Thanks.
