So glad for this forum--got my girls last Mar so this is first winter. I have 2 barred rocks and 3 golden comets. Had a rooster named Rosie but that's another story! One of the rocks, Riley, is dropping feathers and i think she is the one not laying. (only getting 4 eggs daily) She's first in and last out of coop, but is eating. What could be the problem and how to fix? Many thanx.
