I shad to take some eggs that turned out to be cracked and leaking away from my broody black cochin momma and gave her six newly hatched buff orpington babys. all the while she was doing her fussy-mom clucking and tucking them under her bod/wings. I went back out later to make sure all was ok and there they all were - onlysome little butts or tops of beaks to be seen - she is so happy!! She's been a surrogate mom before and always does a great job.
