We do feed the dam's milk... each kid gets their dam's colostrum and milk. We milk for 10+ months of the year and it is the best way to not only build production but as far as breeding for dairy goats there are many that can't make it for 6 months... our goal is milk.

We won't ever tax any doe but we have dairy goats to be dairy goats.

We do't sell our BB to anyone... we rear them on the bottle and sell them either weaned or just about (like down to one bottle but it is more for comfort than need).
For us- unless someone already has experience in bottle feeding it would have to take special circumstance for us to let one go early.
I don't think I could let a BB go to anyone without experience.
These kids are our babies I would be traumatized if something happened and a kid died because an inexperienced owner didn't know what to watch or look for. Things like that happen and of course the new owner is mortified but as a breeder I feel responsible to make decisions for those kids ... I would have a hard time getting over that...
We do thinks a little different from year to year... i might let kids stay on mom for 3 weeks if I have a doe that has all bucks... I don't want to get "too attached" to the future "food". I am not keeping a bunch of standard bucks around so if I dam raise for 3 weeks and then separate at night I can milk in the am... they can be with mom in the day... I get milk 1x day kids grow til wethered and weaned... then they will go on the big land and grow out for food.
Some goats I simply get too attached too... usually bucks so I have to be careful. I keep tooooooo many bucks.
This is one I love so much.... I may wether him just to keep him. He is my smoochie baby. I hug him and kiss on him. He is my boy!
