Four week olds are crazy, aren't they? Flying and running, WOW! We let them out of their brooder cage today, into our "Guinea Room" in the barn (it's a 12 x 12 stall my husband enclosed). They are loving their freedom! Now the little one-week olds can go into the big brooder cage they just came out of in there, and that means no birds in the house, yay! They will all be out in the Guinea Room.
