I absolutely don't know what I am doing...got 'chickens' on Wednesday and discovering as I go that I need a nesting spot and so on. The farmer I got the hens from said that deep litter was best....but I don't know if they will lay there?? I have a high up place for them to lay with just a little dusting of sawdust on it. Should I have that as deep litter??
You'll need nesting boxes in which they will lay...there are threads on BYC that show all kinds of neat ideas for nest boxes out of this or that material or such. http://www.backyardchickens.com/t/41108/show-us-your-nest-boxes-ingenous-design-post-it-here
Deep litter is for the floor of the coop and run and helps digest the droppings so you don't have to clean out the coop for the year, but it's a process that one has to study on so that you can provide the right materials and ventilation in the coop for your climate. Believe me...it's WELL worth the time it takes to study up on it and this thread is a great place to read.
Deep bedding is not the same as deep litter....one is just a place for poop to fall into and an attempt to keep the coop environment dry and clean smelling while the other is an actual composting system that converts the manure into compost while it's still in the coop. I find the deep litter system to be more beneficial and efficient at keeping a healthy coop environment than a deep bedding system and definitely less labor intensive.
Sawdust can be one component of the deep litter system but you'll want a variety of materials that break down at different rates to get the best result....the more variety of materials and particle size you have, the more successful your deep litter system will be. These can be leaves, grass clippings, garden and yard debris, bark , pine cones and needles, sawdust, pine shavings(best if these are not the bulk of the materials), wood chips, straw, hay, etc.
A deep litter system works best on a soil floor but can still be implemented on a wood floor if there is a moisture barrier in place. If you have a little dollhouse style coop and run, it's probably going to be easier to just have a deep bedding system but if you have an actual coop and a goodly number of chickens, you may want to explore the deep litter system....it will make you life much easier and the life of your chickens will be a more natural one, a healthier one.
