Both are fine to give and no need to limit the amount. Free feed pellets and hay (large amounts of hay).
Which is healthier? I'm not 100% but if you are trying to decided which to use, I say go with the one that is easier for you get on short notice. (in case you run out)
Ok thanks! Oxbow is easier for me to get, so if i get a chin i would use that. Ok, Ive been told varied things about feeding, some say free feed some say 2 TBS. I was leaning towards free feeding as im getting a baby
