Mine are in for usually around 12 hours. 18.1hh and underweight JR gets half a small bale of hay and 20lb of haylage, 16.3 and at the right weight Dylly gets the other half of the bale of hay and 14lb of haylage.
Can't remember the weight of the half bale of hay, and the weight of the haylage sometimes changes if we have slightly drier stuff. J basically gets a big net absolutely crammed full to bursting, Dyl gets a full net fairly loosely packed.
