I have plenty of heat lamps. I have no where to put them in the house. We raised and sell broilers and just got our first batch of 100 today for the year. We do 100 every month. I was planning to move the ducks out today as they are 4.5 weeks old.
i had them in the garage before butit got so nasty we moved them out and cleaned it up. I can put them back in there I suppose but would need to build them a much larger brooder.
According to Dave Holderread who has much more experience than any of the rest of us, Storeys Guide to Raising Ducks says for L breed like Pekin they need 10sq foot of space per bird. And access to outside pen on nice days.
