My 6 girls (and one roo) are about 17 weeks old and have been eating grower feed for a while now. I have 2 silver laced wyandotte, one red sex link, two easter eggers, and two rhode island reds (one of them is the roo). They are not laying yet (though my roo is crowing). I don't get into town too often and try to pick up feed when I'm there. I'm currently running low and will be picking up feed later this week. I'm wondering how much grower feed I should pick up vs switching to layer feed. The coop is ready for laying - I got the nesting boxes prepared for them today. But I know that the shorter days and cold weather (nighttime temps in the teens to 30s where I am, but expecting colder this week) can impact the laying. Their combs and wattles have been growing and brightening recently so I wanted to make sure I was prepared! The biggest mystery to me is choosing the amount of grower vs layer feed I pick up this week to last the next month!
