I really doubt that competition would cause chickens to lay more. It may cause my chickens to want more attention - they are spoiled brats.I will also be getting quail in the new year. Your layout looks good. Thank you for sharing. My layout is set and just need time to play in the garage. But my helpers won't be with me. Something about college & a job. Enjoy the time, if not all the help!Cat's in the cradle and all that.
I elected not to stack cages and let the manure hit the ground. Quail outdoors year round since we tend to have milder weather. Details on watering & feeding still in the air. Cup waterers in the lead with no mess homemade feeders. see slightly redneck on utube for details. Looks like he has a decent set up. He keeps his outside also. Missouri - so between us weather wise.
Purpose is meat and eggs and Jumbo Browns are my choice for the feather sexing. If the chickens have competition, will they lay more?
I too thought about not stacking cages and letting manure hit the ground. the bottom cages will work in that fashion, but I needed to stack in order to save space. Four 8x3 cages is a lot of square footage. My birds are in the back of he garden section of our yard. The more square footage I give the birds the less I have for planting. Since my chickens have far more room than necessary and we plan to downsize our greenhouse project, I hope to add the quail without loosing precious gardening space. The chickens will have more room than necessary still, but the quail must be stacked to make it work. I might slant the roofs of the bottom cages so that manure will run off. That would help save me some cleaning work. However, all the cages will need to have poop trays in the winter in the shed or garage.
How many birds do you intend to have? How large will your cage/s be?
