Almost all hens are easy going except for the head hen. She rules the roust. You want a breed with a non aggressive rooster if you even want a roosters. If you go with RIR get the heritage not production. Easter eggers are muts that lay blue to light green color. Other colored layers are Crested cream legbars, auracounias, arcunias these lay various shades of blue. Green layers are Isbars now being called Silverrudds Blues they lay all shades of green. The ee'er can lay a pale green. Then there is the olive egger like a Easter egger it's a mix of a blue layer and a brown will give you the olive. Marens are the very dark egg layers. You have plenty to think about. Pam
