We have 2 adult goats- Nigerian Dwarf/Nubian mix. They are 6 years old. One of them has been bred once, and the other has been bred three times now. We breed our goats once a year, at the most. First, we test our goats' blood for any diseases that can be passes through the milk. Both of our goats are negative on all the diseases (CL, BR, Johne's Disease, CAE, and Q-Fever). After they kid, the babies have access to the milk 24/7 for two weeks. After 2 weeks, they can start eating a little hay, so we separate them from the mother at night, and let her udder fill up, then in the morning we milk her out, but the babies still have milk, as her udder fills back up throughout the day. We use herbal wormer, and so far it works great! You can get it at:

Our goats are kind of picky, treatwise, but they love Ritz cracker, Saltines,maple nuts, cereal. Occasionally, they eat fruits and vegetables, such as tomatoes, strawberries, and apples.
In my opinion, polled goats would be a better choice than dehorning them. We disbudded ours, but unfortunately, their horns grew back deformed. The downfall is that polled goats are hard to come by and usually quite expensive.
Hope these answers help!
