What exactly would udders be like in pregnancy for a pygmy goat? My two girls have a difference in their udders. The one that we assume is pregnant, the sac area is much bigger but the teats are the same. Are the teats supposed to change in preparation for kidding? Or is it just the bag area which gets larger as it produces colustrum? Neither of these goats have kidded before so there wouldn't be something "left over" from previous kidding. Or can one goat just naturally have a bigger sac area? The likely pregnant one- her bag sags about 4 inches down... maybe 5. I haven't measured it. The other one is only about an inch. Just a small pooch whereas the other one is more than a handful. Maybe two handfuls. Any idea ?
