We don't have any goats but I want to buy several Nubians. We have a 60' by 60' metal barn with a concrete floor that we store equipment and feed in for the various animals we have. I want to add on a 25' by 60' addition along one side. The 60' side divides into three 20' sections. The middle 20' needs to be a concrete pad that heavy equipment can use to exit the existing barn. That leaves two 20' by 25' sections on either side of the center path that I can make into areas for the goats. I can have solid walls on the ends or have them open. The open 60' side faces north and we do get a north wind in the winter but we are in coastal Texas so it rarely gets below 30 degrees. I guess I have two questions. First--should I concrete the floor or leave it gravel? Second-should I just have one big open covered area that's 20' by 25' or divide it into two or three covered pens? I was thinking of making one 20' by 15' area on the outer edge and two 10' by 12 1/2' pens so I can separate them if needed. I can make their run as large as I want. Anywhere from an acre to fifty acres.
