(4-5 Month welsummer hen) picked her up and she wieghed maybe 1.5 pounds, and thats giving her a couple ounces. picked her up and again head circles like she has no balance or knew which way was up or what was going on. again immediatly isolated gave water with vits and probios, and wet crumbles, showed absolutely no interest, then passed less than an hour later. does anybody have any idea what is going on here...because while i am trying to thin the flock out for the move, ive already picked the ones im keeping, an of course those are the ones that keep passing. so i really need to figure this out before my whole flock is gone. PLEASE HELP!!!!
