I have a white Holland Turkey hen who is about 7 months old and she weighs 14lbs, i got her at royal king with another Turkey who happens to be a big old 44 lb broad breasted tom, I know there’s a possibility she is a meat bird but everything about her points to white holland. I have noticed recently that she waddles around like a penguin and she has never flown, she also sleeps on the floor. I put a roost in that is very low to the ground just to see if it was something she wanted to do but when I put her on she always lost her balance. Ive read somewhere that it could be a vitamin deficiency but is that true?
