Thanks for asking. Finally 100% well. Flu for the first half of January. In bed for a few days from New Years Day. Then not feeling 100% for a couple weeks. Then caught a head cold a month later,  then tree pollen and seasonal allergies beginning, making me think the cold was dragging on and on. 
The girls are all well 

. A couple pullets, now hens 

, molting in fall and one still not showing laying signs, feathers still coming in. I thought it was odd, but perhaps their breeding contributed to this.
As far as the pecking, perhaps the extra bright light reflection off the snow could be a stressor? They seem back to nice girls..
Spring is almost here, with plum buds and other fruit tree buds swelling, crocus in bloom, daffodils in bud. It's rainy this coming week, after a balmy, sunny, gardening weather past week. Teaser for sure. How are you?
