Wow Carla! What a journey. I started 3-1/2 years ago with four wethered NDs. My plan was to get dairy goats, but I also planned to get two Maremma LGDs, to protect my animals from predators. Do you have any plans to get LGDs? Since we moved here and got our LGDs, we haven't lost one animal to predators. That includes chickens and ducks. I was glad I started slowly, and both the dogs and my DH and I were able to learn together, before I took the plunge and got the girls, which was a lot more complicated.
Given your physical issues, you might want to consider paring down your numbers, so you can better manage the work load, and cost of feed. You can take time to get the boys to weaning age, and then carefully choose good homes for them. Actually, bottle feeding them is really good, because it makes them super friendly, which will make them easy to go with a family, as a pet.
I know it was a hard choice to make, but I think you, ultimately, made a good decision to offer to give the two mini-nubians back to the lady, who gave them to you, and as others have said, you would do well, to take a deep breath and let them go. it is so good, that you and the owner had an amicable exchange of animals. It sounds like you read her well, in that she was more interested in her cows, than the goats. Hopefully, after the experience with the two boys, she will approach finding them a home, a bit differently.
Great advise
@Southern by choice! As I read the journal, I was thinking some of the same things.
The one thing that I might add, Carla, is about a comment you made shortly after you got the two big boys.
I would be careful about giving animals antibiotics, "just to be on the safe side".
** First, we have a huge problem, in this country, with antibiotic resistance, given for this very reason.
** Second, it's important to know if there is actually a need for antibiotics - did they have a temp, lethargy, decreased appetite? Each time you give antibiotics, it increases the likelihood of antibiotic resistance. If there isn't a medical need for it, your are needlessly increasing chances of resistance when you really DO need antibiotics. There may be bacteria present, at the time, which aren't strong enough to make the animal sick, but that may be affected by the antibiotic, enough to be affected next time they truly do need antibiotics.
** Third, it's important to know that the antibiotic you are using is appropriate for the infection. If you give the wrong antibiotic, for the bacteria causing the infection, it won't do any good, and you will only delay proper treatment.
I wish you the best, in your endeavor, with these sweet little boys. Please do remember to take care of yourself too. I know you used to work 100 hours a week, but you are dealing with constant pain. in addition to the importance of keeping busy, to distract from the pain, it's also important to get plenty of rest.
I always find myself much calmer and more relaxed after a "goat sit down session". Might help him mellow and de-stress as well. Hard to stay angry when you have little animals demanding your attention. And they're fun, and interactive too!
