HELP! My turkey won’t grow!!

[Lylaronald]

I have searched online for hours and no one seems to have a similar issue. The turkey is about 2 1/2 months old, and hasn’t grown well sense the beginning and is always pale and when you pick it up is always shaky.
We’ve tried high protein, different feed, electrolytes, probiotics, nothing works.

She is about 1/2 the size of her brother and they are the same age. Her feathers are also messy don’t grow quite right.

If you have any tips, please let me know.

She is probably failing to thrive. What are you feeding her? What percent protein? Exactly what electrolytes and probiotics are you using?
