I have 10 in a kiddie pool together. They are about 2 weeks old. I got one of everything except I got a male and female Cayuga. The rest are all female, black Swedish, blue Swedish, buff, saxony, welsh, silver, magpie, and kaki. In a separate brooder I have a white layer and another welsh. I replaced their heat plate with one that doesn’t tip. Will try to post a picture. I am struggling to keep their pool clean, they wet everything so fast. I tried to introduce the younger ones to the older ones and the older ones started pecking at them immediately. They are in my room. It smells a lot. I change the bedding daily. I separated the feeding area from the rest of the pool and it helped a little. We put up a vinyl fence but there are gaps underneath big enough for them to get through right now. I plan to get a plastic shed and attach it to a run with hardware cloth underneath. When can they go outside? I am in Delaware. Right now it’s not that warm but should be in a couple of weeks. I also plan to get a livestock guardian dog soon. Does anyone have a vinyl fence with ducks?
