I have a 120 square foot chicken coop and it will house 27 chickens when I'm done. The weather is pretty mild here, summers aren't too hot and winters never get that cold. Maybe ranges from 20-100 degrees with few exceptions. I want to get about 5-8 more birds for my coop and I need to narrow it down to guineas or a few more chickens from breeds I don't have. So my questions are: 1) Will my rooster try and mate with guinea hens? Will guinea males and my rooster fight? 2) Will guineas use nesting boxes like my chickens? 3) My run is going to be 5 foot tall(not covered) but have hot wire fencing around the outside of it to keep raccoons out, will my guineas just fly away? will they come back? any tips to force them to perch next to my chickens? I'm a little afraid of them maybe flying into my hot wire fencing trying to get back into the run. I don't know if it could potentially be fatal to them or not. Thanks.
