Very new to keeping backyard goats but we had always had some on the farm I got it that I wanted goats 2 years ago for milk figured just one but of course you need 2 they are herd animals after all and 2 turned into 5. I had them paid for before they were even ready or the pen was even built. I literally had them fenced off while I installed the gate. I went with Nigerian dwarfs as they have sweet butter fat milk and they are smaller. One thing I can say is look into it an plan it out well don't do what I did because it was a lot of work fast and costly as I ended up going with all register able goats so I can sell the kids for more plus I noticed a lot of people want registered for all the paper work so you know what your getting. But at 400$ per goat on average it adds up fast. Plus the registration fees ADGA membership and if you name your goat herd. I installed a 40*70 pen 4' woven wire fence. Fence is one thing you def need to invest in I did most of the work myself and that is a lot. I stretched the fence and clearly shows I didn't know how to do it like a professional as it sags some but for dwarfs its okay but a larger goat I would worry.
So just some food for thought
1 Meds, your gonna need to get on hand meds for them best to watch youtube vids and see what people recommend and why.
2 Feed, you need to know what your feeding, I free feed hay about a slab a day so maybe 1 1/2 bales a week that is for 5 3 month olds but they waste a lot I need to make a better feeder. Also free choice minerals and I feed grains an some pellets about a handful for each goat once for an evening dinner treat I am working on making this a blended mix with less pellets.
3 Billies, if you are milking you need to have you goat bred depending on the goat that is only a few times a year they go into heat are you planning on having her serviced somewhere? I ended up with my own billy but he will need his own pen soon and I have a wether for his pen mate. Billies smell more so breed depending.
4 Kids, what do you plan to do with the kids sell them? if so pricing depends on the registration again unreg here goes for 100-200 reg 300-650 was the highest I saw this year for 4H quality.
5 Milking, have you ever milked? I hand milked cows when I was younger helping on the farm so for me no problem but if you have never do it before it will be a fun day lol
6 Time, while they don't actually take much time up you will find yourself spending it with them I just like to sit with mind some in the evening let my dog run in the pen and brush them when they walk over the more time you spend with them the friendly they will be an better at the milking stand, brushing tends to put them in a simple relaxed state I found. Along with that just time to care for them I am trimming the hooves 2 times a month as they are growing like weeds right now and I want to stay on them as it is another rainy spring. This like milking isn't hard just need to learn how to.
Don't let any of this stop you tho if you want them just put in the research and don't jump in all at once like I did lol everything online may be a lot to take in at once an d overwhelm but like most stuff you pick it up easy as you go.
