Well, my babies (4and a half weeks) moved out of their brooder cage today. They have their own fenced off section of the hen pen and a refurbished dog house for a mini coop. They are sooooo happy. They're acting like real chickens. Running, flying, dustbathing and scratching for bugs. And they are actually friendlier now, letting me scoop them up for a cuddle. I love my babies.
