Recently purchased 16 chicks at Atwoods in Shawnee. supplier may have been Murray McMurray. Three have crests and look like they will be either golden lace or buff colored. At two weeks old, the crests are becoming more feathered. Questions: Are Crested Polish standard or bantom? They are a little smaller than the Barred Rock and Australorp chicks. If these are crossbreeds (which sometimes happens), what do I look for to determine roo or hen? Are there any feed considerations for these very healthy babies when they are older? Even if they are not big egg producers, they are darling additions to my little flock.
