The subject line says it all. The chickens I got last night are younger than I expected. I have one year-old hen, and three exactly 4-month old pullets. But because I was expecting them to be older, I only bought Layer pellets. What is the best option for feeding these chickens between now and Wednesday when I get back to the feed store for Flock Raiser? For tonight I put out just scratch and greens. (And I assume the mature hen will be OK on flock raiser with free feed oyster shell until the pullets start laying - let me know if that's not OK.) Thanks in advance!
