An 8 week old should be free fed until she's about 6 months old.
I feed my Mini Rex 1/3 cup of feed a day, give or take. They get half in the morning, half at night. It probably adds up to a little more than that.
Standard Rex get two 1/3 cups 2x daily...I don't know my fraction math, so no clue what that really adds up too! lol. I suppose I could dump that amount into my larger measuring cup and see, eh?
And then everyone under 6 months gets free-fed pellets.
Hay and alalfa (alalfa to the Rex only, though I know it is good for all babies...) is given in the evenings because otherwise they'd waste it, and even at that, I'm still going through nearly 2 flakes of hay a day.
