I'm happy to see the lights get used. We used to be good little decorators and put them up on the house every year. Then we got lazy and figured that it was good anyway, since then we weren't using the electricity. Now we're using electricity for a good cause, not throwing these in the landfill and not buying anything new. Pretty good option in my book.
The plan for next year is to get more chickens. We want to build a bigger, more permanent coop for all of them. The tractor would still be used for the new chicks, until they're big enough to go into the larger coop. We can also use the tractor to graze them when it suits our purposes. The long term goal is to not have to supplement them with light over the long term. If we let them lay like crazy during summer, then we can preserve the eggs for the winter. I have no idea if this will work, but it would be great if it did. Eggs keep for a long time and can also be frozen if need be. Has anyone else done this and had it work?
