I was told a pullet molt was kind of light, but i have one who is pretty weird looking right now, and feathers everywhere. her 2 hatch mates are molting a little but this one the biggest and strongest of those 3 I'm afraid will get cold soon, she also is kind of segregated from the others like they won't have much to do with her while she looks weird ? Needless to say these 3 have also quit laying . How long does a molt last? do i need to get this near naked hen a sweater? I assume that they should get 'back to normal'? soon?
