We are buying part of the property next to us in order to expand our pastures. half of the new property is "pasture" BUT over half of that "pasture" it is very thick blackberry brambles... There is easily a full acre of them. That is the area that we are fencing off first. We figure that the goats (4 nubians.. and 2 llamas) will rid us of all of the brambles but I am concerned that they will overeat and hurt themselves (it still freaks me out that they can eat all of those thorns). They have never been exposed to the blackberry bushes before. Two of the girls are pregnant so I am super protective of them as well... but I don't want anyone to bloat or have issue.... and they are the type that will continue to eat hay no matter how much I put in there. How should I handle this? Just let them eat it all they want or limit their time in the new pasture?
