My broody frizzle bantam is so very thin. She is on day 13 of sitting. Is it ok for a few days to give her the chick starter 24% to help her out?? She does not eat much as she will only come out for about 10 min and she is more worried on chasing others away from the food rather than eat. Is this normal????? she is my favorite and I do not want her to get sick.
