Last year, I had a chicken egg that magically appeared under a turkey hen and I didn't know until the baby chick had hatched. Well, I decided to let the turkey be the mama of the baby chick, so the baby chick ate the same feed as the poults. I always feed Purina Game Bird Starter 30% protein to all of my poults, so the chick ate the same thing as they did. The baby chick was fine. Although he grew at an unusually fast rate and he was a Big Ole Boy, to this day, he is healthy with no problems. He only ate the 30% protein for about 4 months and then I switched him because he was getting to big. He is
THE largest rooster that I have in my chicken yard. Every person that stops by is amazed at how big he is. One guy offered to buy him for $50.00. I told him no. My boy ain't going nowhere!
Here is a pic of him below. This pic was taken last year. I think he was about 6 months old in this pic.
In this pic, he is having a boxing match with my turkey hen. My Tom is just standing by. My rooster is about a year old in this pic.
So, your chicken will be just fine. She just had one serving.
