Need Red Boer goat care instructions.

I need some advice and directions. I have 2 does, 7 mo and 5 mo. Planning on raising goats to sell. I am really confused about the info I have read, and heard from the 2 breeders I bought these 2 does from, regarding care.

1. One said feed #1 coffee can full of feed a night (Lucy, the 7 mo old, was 4 mo. at that time). Bought Bella (5 mo old) 2 weeks ago. Her owner said 1 cup about once weekly, that the other breeder was losing a bunch of does from over-feeding grains. They have plenty to eat in their pasture here. We are feeding Lucy about 1 1/2 c nightly and Bella about 1 cup nightly.

2. Neither one said anything about hoof trimming, but I'm seeing several posts about it here. I found a website that said if they have big rocks to climb on, that they may not have to have their hoofs trimmed. BTW, one breeder did have a pile of huge tree trunks in the middle of his pasture. Don't know if that was intentional or not. Their pasture is mostly hard clay and they have a stack of pallets to climb on.

3. Both breeders told me they had both been wormed. I read they need wormed frequently, bi-monthly to quarterly. What do you all use and how frequently?

4. What is CD&T, free choice minerals and 18% protein tub? And what is it used for and how?

5. What about the tags? Neither of these were tagged when I bought them.

6. Regarding breeding; 2nd breeder said I should wait till January to breed them. Lucy would be 11 mo and Bella 9 mo. I'm also planning on getting a few more about 5 mo. old does by the end of September. At what age can I safely breed the does, and how old should the buck be? Their health and welfare is a major concern of mine, and I don't want to go about the breeding in way that is detrimental to their health.

Thanks much! Robin
