I have two 3 week old pigmy billies. I bought them last Saturday, and was told they were born July 7th but the mom dies a little over a week ago. I was also told they were in the bottle already. I've tried two different nipples.. I'm being kinda forceful.. I hold them and open their mouths and try to hold the nipple in there.. All I can get them to take is about one oz each! What am I doing wrong? Do I just keep trying!? I've had goats before, heck, I've had bottle calves before, but not bottle kids.. Thanks for any advice!
