My different
opinion
: Her horns are making a nice sweep to the back...if you don't have a problem with them...it is how goats are - naturally. Pack goats and cart goats are usually left with horns because it is how they disperse heat, goats don't sweat. Angoras must have horns as well. Teach the kids a healthy respect for her horns, and don't ever push against her forehead or play butting games...They make very nice handles for catching or leading without risk of choking the goat. We have children and goats and sheep with horns, and have had no issues. The biggest danger we have found is to the goat...they can be so determined to get what is on the other side, horns can cause an entanglement risk...but I've also seen them very adept at extricating themselves.
If her udder is filling up, keep an eye out for babies!
I think you can give Positive Pellets (a wormer) even during pregnancy...always check your label. If she is doing well, and possibly pregnant - I wouldn't be so quick to do it. If you can make the investment, your vet can do a fecal test - here they run about $26. Kidding will usually trigger worms, too - so if she kids, worm after kidding. Remember that worming will cause her to shed viable worm eggs, so you'll want to strip the bedding in that area after 2-3 days to minimize the reinfestation. Do you have an experienced goatherd nearby that can take a look at her "in person"? They could evaluate her condition better seeing the whole goat, and getting their hands on her....
Congratulations! I hope you and your kids have a great time with your new acquisition. Have you considered 4-H?
