you need to catch that doe, keep her in a small pen and force her to accept the baby. hold her still, tie her up if necessary.
if baby is weak and/or dumb, you will need to put her onto the udder, force the teat into her mouth, and may even need to squirt milk into her mouth if necessary
if baby is very weak, you may need to milk the doe into a bottle, and bottle feed her, or use a syringe, or even a stomach tube if she is really weak
by 12 hrs she should have had at least 6 small feeds by now. you need to get some food into this baby now or you will rapidly run out of time. if mum is a dairy breed she also needs to be emptied otherwise you are going to have problems with both mum and baby
if the doe was going to have more kids, she would have had them by now, they are usually 5 - 30 mins apart. if she does still have more kids in there you would have a very sick goat by now. she would be depressed, lethargic, may be standing up, sitting down, standing up, sitting down etc, and may or may not be pushing
did she drop the placenta when she kidded yesterday?
now the kid, are her sides hollow? or is her belly rounded. if its rounded she has had a drink when you werent watching. if its hollow she's starving. does she constantly cry out? if so, she's hungry. or does she seem content and spend a lot of time sleeping, tucked up in a warm spot? if thats the case she has probably had a feed
I dont pull to bottle feed unless I have to; I force the does to accept their kids by tying them up for the baby to suckle, teach them their responsibility
