This morning I found another chick hatched, but it was attached to the shell by a weird gloopy lump. I thought it would get better if I left it, but when I got home it was dead!It had a red lump on it's bum and there was more red stuff on the straw. Any idea what happened? It was hatched by a broody hen. I just want to know if there's anything I can do in the future!
