Hello. I am a new goat owner to two Nigerian Dwarf females. They are about six weeks old and approx. 4 weeks post disbudding. I have been reading that their scabs should have fallen off by now. Is this true? They do scratch their heads against things, so I know the scabs must be itching them. I also don't want to pull off the scab like I've read some do. Can someone offer me advice on this topic? When should they fall off? Is there a time I need to take them to a vet? Thank you!
