I want to try raising the CX birds in the spring when tractor supply sells them. I only plan to get 12 and I will let them spend the first two weeks in the brooder I keep in my regular layers hen house since there is already electricity and it is easy. But after two weeks I am hoping it will be warm enough that I can move them to a fenced in area right behind my house with the dog away from the layers. It is about 30x30. I figure the dog will protect them from predators so I dont have to worry about securing it as long as they cant fly away. From what I read there is no way these birds are flying over a 4 foot fence right? So my main worry is that 30x30 is not a big enough area to totally grow them out. Is the whole yard just gonna fill with poop and be totally disgusting? I had 9 layers back there one year and it was fine till my dog died and they all got taken. I didnt even notice the poop then. But everything I have read is that CX birds are so gross so I am worried about that.
