I have two 18-week-old guineas that have been housed with my chickens for months. They roost, eat, and do everything with the chickens. The problem I have is that they are getting more & more aggressive with the chickens, esp. the newbies. I add new chickens to that coop when they are getting ready to lay. I have two separate coops that are side by side where they can easily see each other as there is a metal fencing separating the 2. When the newbies are added, the guineas are really mean and relentless. The guineas constantly try to intimidate and pick on the others through the fencing too. There is constant chaos . . . to the point where my kids want me to get rid of the guineas : ( My thought is to make a small coop and let them just free range. I keep the chickens cooped up in their run until about noontime and let them out into a fenced in pastured area with the guineas. Lately I've been letting the guineas go out in the fenced in area as soon as they are let out of the coop, keeping them away from the chickens. They just pace back & forth until all of the chickens are let out -- for hours they will do this. They could easily fly away and free range as the fence is only 4 feet high. They have become 'chickenized.' Should I make the effort to make another separate coop for them? I'm just not sure how we can reduce this chaos & aggression with the guineas. I always do the addition of newbies at night when everyone is sleeping. The chickens don't seem to have an issue with the newbies, just the guineas. Any ideas or suggestions would help. Coop ideas would be great too. My husband is a carpenter, so I can get him to make whatever I need. I just don't want to waste his time & materials for something they will not utilize. And don't want to make something too big for them. Thanks.
