My Olivia was let out of broody coop to free range w/ her 4 babies. SOMEHOW the big girls run door flew open A N D all H_ll broke lose' She(Olivia) was whamping on everyone. The babies were screaming and running all over... Earl our roo was absolutely paralyzed w/ fear and I was also screaming for help as I stuffed 2 chicks in my pockets and chased the other two. Needless to say NO ONE heard me, and Olivia went after one hen and then another. She had been chest bumping through the shared fence for several days but there was feathers flying now. Somehow I got her back into the broody pen and captured all the babies. What an experience... Do all broodies do this? Her last clutch she left when they were feathered, then I inter-graded the house chicks into the pen... all about the same age. Is this new behavior because the babies were littler?
