Today we finished their new house and installed in ground pool. ($7.48 at Walmart) everything was good to go and we put our 2 ducks in the run. We had 7 bantam mixes about 16 weeks old, 4 hens of various years, and a 3 year old banty roo. The little bantys charged and attacked both ducks, it looked like a rooster fight on TV, even the older hens were jumping and kicking at them. It was crazy. I was able to separate them but man, I admit, I was hot.... The ducks have grown up with a batch of 12 red mixes. They are best buds and snuggled in their cage until I moved them out this afternoon. The chicks love them until they come in from the tote and shake the water off in the sleeping area of the brooder. Madder than wet hens takes a new twist there!! Anyway, I was planning on harvesting the older birds later this year. That happened tonight. Tomorrow the babies who happen to be fully feathered now inherit a almost empty coop. We left 3 banty hens. So, here is the question, has anyone else had problems like this with ducks and chickens? I haven't read of anyone having this problem. My birds turned downright nasty and aggressive. It was weird! What happened? The other 12 are the size of the bantys already so I'm not worried, they grew up with the pekins so the integration there is a non issue. Anyone know what went down with these guys and gals?
