While I was at the beach on vacation my two bantam hens went broody. Both were sitting within inches of each other ( I believe some of the eggs were messed up while they moved em around.) Then hen that went broody after the first one had chicks within a few weeks , but the hen that had set first...
You've had more than one hen die from this before ? Could the previous hen gave your older hen an illness ? If not ill Google it and see if I can get you an answer what was all the symptoms ?
The hen I would keep quarantined for 2 weeks ,but the chicks I would keep quarantined for a week except the droopy eyed one. I would tried and find some answers as to what was wrong with her/him.
