I got this white leghorn hen as a "rescue" in March 2010, and in the time she's been here she has never molted. She has the feathers she came with, and is getting very patchy and scraggly. My suspicion is that she is a "Pearl" production leghorn from McMurray hatchery, and there may be some genetic issue going on. They have been playing with making a longer laying hen, and in so doing maybe they found a mutation that halts or delays molting. Since molting hens don't lay, it would pay for them to make a hen that doesn't molt, yes? I guess that would be okay for battery hens (grrrr) that are kept in a climate controlled setting, but my poor girl is living in a barn and run with her pals. If it weren't for the molting problem she would be a happy camper. The genetic thing is my best guess, but I am wondering whether anyone else has ever had this happen, and if so did the hen ever molt normally? I may have to get some of that polar fleece and make her some clothes if she can't grow a new suit herself.
