I have 16 Guineas that are a mix of 20 and 10 wk olds. I just put them in a big coop where they have plenty of space and roosting options. They also spend the day free ranging outdoors. I would like to introduce laying hens now for eggs and am wondering about the potential issues I'm facing. My friend has about 10 he is willing to let go of for me. Am I potentially entering into a big problem if I roost them together at night in the same home??
