A friend of mine has Polish Top Hat pullets and needs to place them (2 and I believe they are 2-3 weeks old) I am new to the chicken world and I have 5 4 week old chicks. 4 are BO and one is a NH. I think the NH is a roo. Is it not good to mix these breeds? They are all very young so I was thinking this would be the time to mix them in my coop. Does anyone know what they look like if they breed together? I also heard Polish Top Hats are friendly when they are older. Is that true? My chicks are all very sweet and I did my research before I hatched them. I have to know by tonight and I don't have much time today to research so I'm hoping to get some great advice from my fellow BYC members. Thanks everyone!
