Are you bottle feeding this baby? Was it bottle fed at the breeder's farm? 7 weeks is awfully young to be weaned from Mama. If it wasn't bottle raised then you have 2 problems going on. It is lonely, and it want's it's Mama. One can be solved by getting a second goat about the same age. The other can only be solved with time.
The thing about goats, and many people forget this in their rush to get the cute little babies, is that they aren't dogs. They can't live a solitary life out in a pen beside someone's house.
A solitary goat:
Is Noisy
Escapes
Destroys it's surroundings
Fails to Thrive
Forgets how to be a goat and will not bond with other goats later in life.
Did the breeder teach you how to take care of the goat? How and what to feed it? What not to feed it if it is a wether (Has been castrated)? How to care for it's hooves? What vaccinations it needs and how often? Anything about worming?
If it is eating solid food, hay or forage it needs to have it's first dose of wormer by now. Follow it up in two weeks with a second dose.
By ten weeks it needs it's first dose of CD&T Vaccine....followed 3 weeks later by a second dose.
If your little one is a wether you need to keep the grain to a minimum or you will risk kidney stones. Keep feeding a majority of Hay and Forage. There is speculation about ACV (apple cider vinegar, but not the kind in your kitchen - get it at your feed store) lowering the risk of stones. You can look up here or on Backyardherds about putting it in the water. I don't do it but personally, apple cider vinegar does a lot of great things.
Hoof care, hoof care, hoof care. Start holding your little one and playing with his feet now, while he is lonely. As soon as the hooves start over growing, start trimming. If you don't know how, find someone to show you, or hire someone. You don't want him/her to suffer through hoof rot.
If you can't afford a second goat, and that may be your Mom's problem, Petfinder's has livestock on it and you can find goats galore looking for homes there. I would really consider it because If you ever need to rehome this little one, it will never fit in with a herd if it doesn't learn how to now.
