I need a crash course in ducks 101. I have chickens and have learned so much from this site. I am calling for some duck people wisdom now. I have a few questions, but if you think I left something out that I should know please feel free to school me. 1. Do duck breeds get along? I was thinking about calls and standard breeds. Will the smaller breeds be ok with the larger ones? 2. Do ducks need nesting boxes? I have read yes and no. What is your opinion? 3. I know duck eggs take longer but can they be incubated with chicken eggs? I have a seperate hatcher, so eggs are moved for lockdown. 4. Are drakes aggressive towards eachother like roosters? 5. Do they need to fly? I was planning on netting the top of the pen. It will be about 7 foot high. 6. What about food? I read you can just add wheat to their feed. I feed Tucker Milling Super Lay 22 to my chickens. It is a 22% protien layer pellet. 7. Do they need a roost or do they sleep on the ground? 8. How large a pool do they need? Sorry for all the questions. I have been reading and have read contradicting things. I thought it might be best to try amd gain some knowledge from experienced duck people. Thanks for any advice you can give me.
