Yes she is very old. But healthy. She will jump out of the brooder and waits for her chicks, they can't jump out yet. Then she jumps back in. Whenever I put my arm on there to do whatever she attacks me.
I have my 13 year old Polish Tophat hen in a brooder with her 4, one week old chicks. She was always a free roaming girl. Now she is cooped up with her babies she seems very mad. Should I let her roam with her chicks in a protected horse stall? Or leave her be?
