Also I would reccomend feeding her some wet mash just to get her some energy. Glenda L Heywood gave me this recipe:
natural probiotic recipe is is:
3 tbsp of dry crumbles
4 tbsp of milk, sweet, sour, or buttermilk or a mixture of all or some
1 tbsp of yoguart of non flavored yoguart ( no artificial sweetmer)
mix good
AFTER PUTTING VIT'S IN
PUT 1 TBSP OF APPLE SAUCE FOR THE WET MASH PROBIOTIC
NOW THE IMPORTANT INGRIEDIENT FOR EACH CHICKEN FED
and add 1- 400 mg of Vit E for chicks or
( USE 1,00 mg of Vit E for adult chickens)
by cutting the end off the vit E capsule for each chicken fed this wet mash
putting Vit in the wet mash
You can also feed her some mashed up boiled eggs.
