My almost 7 week old barred rock pullet (I hope) suddenly developed round bumps on either side of her face - under her eyes. I swear they were not there this morning and definitely not last night. She is inside during the afternoon and at night and outside during the warmer part of the day. I don't notice anything else wrong with her. Is this a normal part of development or is she sick? She is with 4 other chicks - none showing any signs of anything.
