I have my ducks in a 50 gallon tote. There are 6 of them about 2 weeks old as a guess, I got them from tsc. They are growing quickly, so at what heat temp can they go out in their house without heat to brood in? Or do I need to find something bigger for another few weeks? We are building the house in a week. The run will be built thereafter. I know they need to be fully feathered to have free run of the outside. Do they start to pick at each other or themselves if the area gets too small, like chicks. I'm not trying to keep them in a small area just want to know where to go from here. 4 pekin and 2 either chocolate runners or khakis, we dont know yet. 6 total. I am attaching the setup now and size sticker.
