Hi, I just bought 2 three week old Guineas and placed them in the brooder with my 1 1/2 week old Buff Orpington chicks. The Chicks are eating the Guineas feed and the Guineas are eating the Chicks feed. Will this harm them? The Guineas and Chicks have never had anything but their feed to eat. I am concerned this will harm them, but not sure what to do. I don't want to have to buy another brooder lamp and separate them, but will if I have to. I was hoping they would get used to being together.
