Howdy from Texas!

Hi everyone, new member here from Hondo, TX about 30 miles west of San Antonio. The wife and I have been considering adding a few goats to the family and came across this forum and it looks like a good place to get some questions answered and do some research before diving in. We have about 6 acres that is fully fenced (although I am not sure if the fencing will stand up to the goats). We have a pecan orchard of 100 or so trees (any issues with the goats/pecans?) and a barn where we could put some pens (do they need individual pens or is a communal pen okay?). We were hoping to let them roam the entire property but it may be better to have a smaller dedicated pen. Just a few of the things we need to find out, along with the best breeds for Texas. Thanks in advance for all the help!
