I think 350 to 450 is average. She was a slow starter and my friend produced her. After almost a year of force feeding she is now eating on her own. She is less than 200 grams and was produced in 2018. She practically gave her to me knowing that I would give her a good home and she has not missed a meal in my care as of yet. She also handles well. No sign of wobble but I do expect it. Just a lovely lady.
