It is stormy and rainy - I know it is too soon for my Week-Olds to go outside, and weather is not cooperating. But what weather is OK, and How Old to put them out on the grass? Buffs, if that makes any Difference. Next - Floorplan of Coop is 3 Feet By Six Feet, with Two "Outsticker" Nesting Boxes that are 14 inches Square.....Is this too small for EIGHT Buffs? Thanks In Advance for Responses.
