When to stop Chick Starter and begin Layer feed?

[SCchickens2011]

When do you stop feeding Chick starter and begin Layer feed? My girls are just about out of a 30# sack of Chick Starter and I was thinking they may be too old now and should begin feeding Layer feed, they are almost 2 months old.

You have months to go. They can stay on starter/grower until they are close to laying age, about 18 weeks old, or they actually lay the first egg. DO NOT begin layer feed at two months of age. Way too much calcium for them!
