I would imagine the chickens need some help in the matter of building up the bodies
wet mash probiotic
I personally would give them some
**wet mash probiotic with vitamins in it
3 tbsp of dry crumbles
1 tbsp of yguart
5-1/2 tbsp of milk any kind
add the vit's to this and feed him this
twice a day
and see if they will get better
**ALSO this is important to do
buy a bottle of VETRX
and put vetrx on their heads and under their wings
and 1/2 tsp daily down their throat
and 1/2 tsp in their drinking water
do this daily till the birds are not having moisture at their nose
also keep them away from other and other birds
do their chores last as you can carry it on your shoes and clothing and hands to the other chickens
you can get vetrx from smiths poultry supply
