hi all, this is my first post and im after some advice

. i have five lambs that are 7 weeks old, they have been cut down to two milk feeds a day and my plan was to do this for a week and then drop them down to one feed a day for a week and then stop the milk feeds completely. is this an acceptable way to do it as they are eating hay and creep and are drinking a reasonable amount of water as well.
this may seem like a novices question but this is the first year of keeping lambs so i would rather ask a silly question than make a mistake and cause any suffering or harm.
thank you in advance.
Maurice
