It is really cold here and i have been doing a lot to prepare for the next couple of days. I realized that on the back of some of the chicken's necks where the feathers are more like quills there is this white powder attached to the ends. It looks exactly like soft, thin frost. Anyone else out there experience this? And if this is frost than does this indicate that they are really not as warm as I thought? Only some have this to remind you and it doesn't seem to bother them none. They don't huddle on the roost at night either. ANY info would be appreciated.
