Today I noticed three of my hens standing around pecking at something. Upon closer inspection I discovered that they were pecking the fourth hen. The "victim", a Wellsummer, was buried halfway in the litter apparently dust bathing and seemed to have no problem with the other three pulling out feathers from her back. They were all hatched in early April so they are (math, math, math) about 8 months old. The feathers seemed to be coming out fairly easily so I'm guessing this is molting? Of course I'm getting ready to leave town for a couple of days and won't be able to monitor the situation. Anything to be concerned about or should I just wait and see? At what point do I need to be concerned?
TIA,
