lacyblue, I have them on 18% protein and I've been adding minced raw liver or brewers yeast or scrambled eggs etc every few days.
I'm not really prepared yet for snow - we have maybe a foot or so forecast beginning tomorrow night.
I still want to block off under the coop a bit more on the north side, and add a little more wind protection on the west side. Also want to add in a second heated water bowl . Always a little adjustment as the season and the flock sizes change - to figure out how much water, etc. I already miss the summer when all you had to do was have multiple water sources and multiple feed bowls and not worry.
Now, closer quarters+fewer choices = a little more squabbling = stress= less than optimal health.
Yep... I keep adding feeders and waters, moving them around so no one gets bullied out of eating when they want... Summer is sorely missed.
