Ok, so this is what we have going on... 8 hens (mix of egg laying breeds), 1 rooster (plymouth rock) and 2 Pekins (side surprise and not part of original poultry plan). We started a very cool 8'x8' coop (3 nesting boxes inside) with 10'x10' covered dog run attached for outside scratching, foraging and playtime. Flooring will be linoleum with pine bedding on top and straw in nest boxes and ducks' sleeping corner. Right now they all share chick crumble from a 30 lb feeder, common waterer and common grit holder. Everyone gets along wonderfully! These are my biggest concerns: 1) When the chickens are moved off of their chick crumble and move on to egg layer feed, the ducks will also move from the chick crumble to duck specific feed... How do I keep the feeds separate in the coop? 2) Although the ducks are so very cute, they do an amazing job at getting water all over the floor of their brooder... Just natural, but what a soggy mess I keep cleaning up! How do you keep the coop floor dryer with ducks making such a water mess? So much water, I don't want it to damage their feet, create mold, etc. 3) When making the ramp for poultry to get in/out of the coop, what angle incline can ducks walk? The coop is raised off the ground for predator purposes, but the ramp needs to be user friendly for chickens and ducks. 4) Any other suggestions for keeping these guys together including interior design set up or items I need for them? Thank you so much!
