Hi about a month ago my hen was acting sick, not eating for a week, looked weak.... Took away the pellets i was feeding it and it got better by weeks end. This happened months earlier too and in same fashion. Sudden onset. Day before it was fine and then next day weak and no appetite. I will never feed it commercial feed again Giving it wheat, gmo free corn meal with vitaminpowder mixed inas ut is currently shedding feathers.... I want to de worm it with peparazine as ithas never been wormed and uts near 3 yrs old. Is it safe to worm the hen now when its molting...?
