Hi, I have 19 Buff Orpington Chicks that are 1 week and 4 days old. I am very worried because I brought in 2 baby Guineas today and I think they had fleas. My Chicks were fine until the Guineas arrived. Now everyone in the brooder is going crazy picking at the bedding and each other. Earlier I felt something crawling on me and it was this really tiny black thing that jumped off before I could get a good look. I was told the Guineas are 3 weeks old. Do you think they will eat all the fleas? Will my Chicks get sick from this? These are my first Chicks and now I am so upset and worried. What should I do? Should I return the Guineas? I don't understand how they can have fleas? I thought they ate bugs?
