Feeding of Baby Packgoats

[Bowslayer2]

I just got 4 one month old baby packgoats on Friday. I am bottle feeding them 16 oz of lamb milk replacer (can't find goat replacer) twice a day. Once in the morning and once in the evening. I have water available for them at all times and alfalfa as well. This is the first time with bottle babies and I could use some help if possible. I want them to grow BIG and STRONG and healthy.

- How long should I feed them the milk replacer? They are one month old now.
- Should I give them any grain or other feed?
- any other suggestions?

I appreciate any help...I also attached a picture...they are fitting in well and my daughter spends more time with them than us.....
