I need some help too. Some of my girls are chilling in the coop kind of fluffed up and sad looking. However when I go to pick them up or offer them treats they go back to normal for a bit then hunker down again. It's starting to get cold out but most of the flock don't seem to be doing this.
Also, one of the normal acting ones has a runny nose with clear snot which she kept wiping on my sleeve.
I'm leaving the one people sized coop door open for ventilation but the humidity is still kinda high.
Also the current bag of feed had a moldy part, I threw out most of it but the remainder seemed fine and didn't smell like mold so I gave it to them. Was that a bad idea? Any advice to avoid further illness?
