I posted this in the Guinea thread too so hoping for a few answers from some folks with experience with both. I just want an opinion or two from people who have both ducks and guineas. I currently have both, they are about the same age and were raised together. In reading I have read that both the ducks (muscovies) and guineas are both aggressive during breeding season and will go after other birds. I am wondering which should I be watching more closely. I currently do not have anywhere to house them separately. I am surprised at how they seem to have similar behaviors though. An example is when one of the ducks is separated from the others it will start calling and making a fuss, just like the guineas do! The guineas will follow the ducks into the brooder house in the evenings also. I hope this continues, they are a few months old, so I don't know how long it takes for them to start to wander. Any experience that anyone wants to lend would be greatly appreciated! Thank you!
