We're very new at this. . Hatched four chicks about seven weeks ago. . One was smaller than the rest.. now she seems to have stopped growing. . Sneezing frequently. . Good appetite .. normal drinking and poops.. today I noticed blood on her beak .. coming from her nostril.. then more on one toe.. and blood on the bedding. . She doesn't seem to be picked on and there's nothing for her to injure herself on.. I'm getting very worried. . Could she make the others sick. . Please any ideas would help greatly. .
