No not 2-3How do you give them?
Like 2-3 drops of liver tonic directly to mouth and powders with water?
2-3 drops for a full grown aged chicken is nothing
I use 0.25 ML once in a day for 3 days if there any infection related with mycotoxin you should continue for 4-5 days improved behaviour shows by 2nd day
Rest other are provi boost Multivitamin 1 drop for a 4 year old rooster
And pinch probiotics dilute in 30 ml of water
