The literature on this topic is all over the place and all recommend different strategies, I have been feeding mine greens on a daily basis and letting then graze on them as they want throughout the day. I just place a small handful in a bowl in their Set-up, and they eat as they feel like it. Other than that I tend to throw a small bit of other fruits or veggies like bell Pepper or Papya in for them every other day, and every Friday they get a bit of Protein. Any suggestions or improvements?
