We all are learning. Its fun to be new..and enjoy those goats. The fecal is the box that you need to put the berries in. The results will tell you how many & what kind of worms the goat has. So then you can decide what wormer you need.
Yes the carrot can be used as a treat. The hay, pygmie mix , is what they both will need. Lots of fresh clean water to drink. Its sounds to me you are a :great: goat mom. Hang in there!
