Thanks every one for the help with my last post, I really appreciated the help. Now a new question, I ran out of my grower/finisher, I only have 3 pullets and 4 guineas, 2 of the pullets are 14 weeks old the others are 15 weeks, can I start them on layer or just get another 50# bag (doesn't come less) of grower/finisher and use it up then go to the layer? Thank you
