I have recently noticed that one of my Bantam hens is bare underneath. The rest of her feathers are intact and has no signs of lice or parasites that I can see. She dust bathes regularly and is eating/drinking normally. I believe that she is molting as she hasn't laid eggs for a few days, however she only laid her first egg a month ago and would be well under 6 months old. It is also the middle of Summer in Australia. Do you think she is just molting, or could there be another cause? Thanks!
