Hi, I have a 7 week old chick that's pooping blood. She is not acting strangely otherwise. We have 2 new chicks that are about 5 days old and she doesn't get along with them. She used to be the baby in the house. She mostly eats wild bird seed and sometimes eats human food with me, like apples, rice, pasta, citrus fruit and so on. I can't get to the vet so what should I do?
