Now that we are back on Daylight Savings and the days are getting longer, I figured it was about time to kill the extra lighting anyway, so I guess I will do that starting tomorrow. Unfortunately, we can not let our chickens free range which I really hate (too many dogs, coyotes, and hawks passing through).
We do supplement with lots of things the chickens might find if they were able to free-range. We give them grass/weed clippings (we don't have a great lawn--LOL!), all sorts of bugs or worms that we come across outside. Of course, their run is just dirt, so I also put a few pieces of plywood out on the ground to turn over every few days...usually lots of bugs under them.
I keep fairly good check of the vent area, and none seem to have a problem in that area. Hopefully, we will not have to resort to that, but I will definitely keep it in mind.
Any suggestions on some specific ways to "keep them entertained"? They have access to the run everyday from mid-morning until after dark. I throw some scratch out in the run to keep them busy in the morning. Around mid-afternoon, I give them some sort of treat--lettuce, fruit or some scraps from the night-before's dinner. I also give them their evening treat around dark which is something like mash--usually oatmeal or rice mixed with yogurt and flax, but sometimes I use some other base like couscous or enriched noodles. Tonight they got a couple spoonfuls of cottage cheese mixed with flax.
Thanks so much for the info. and any suggestions for enrichment would be greatly appreciated!
