Hi I've had hens for a few years now. I keep them in tractors (one is 4'x8', one is 5'x8' and the last is 4'x16') I have a total of 9 chickens in them. Chickens are great for eggs. Sure. I have a/an egg eater in the big tractor, which has 4 hens in it. I also have had several go broody on me this year, resulting in less eggs. I don't have fertile eggs to hatch, and don't want to add to the numbers in the coops anyway. I have a vicious sebright hen, who crows and lives in the 4x8 with a bantam old english game, who is her best friend. I have tried very carefully over several weeks to introduce more hens to them and the sebright will attack and tear them apart once I release the newbies from their pen inside the tractor (and I leave them in there for weeks!). They are also noisy! cackle before laying an egg, cackle because the favorite nest box has another hen in it, noisy because they laid an egg. LOL I'm about over chickens, honestly! So for those reasons, I was hearing great things about ducks. They're quiet, lay better than hens, and don't mind new additions to the flock. How can I convert the tractors for the ducks, what do they require? Right now the tractors are 4 season, with a roost on one end that is a little 4'x2' coop with 2 nest boxes on the end. Do they need a nest box? Do they roost or do they just lie down and huddle? Also, for water, do they need an open water source? Would a rubber feed bowl work ok for water? I'm not sure when/if this will happen. Currently this set of girls in the 4x8 and 4x16' tractors are just over a year old. the ones in the 5x8 are 2 months old. What about feed? What do they eat? What do you use for a feeder? What are your thoughts ducks vs hens? Thanks!
