We built a greenhouse this winter for the first time and planted lettuce about a month ago. It's been growing great so yesterday I gave my gander a treat (he likes lettuce but our goose doesn't) and let him graze in the lettuce bed. I would swear he was smiling!! So today we pulled all the grass and even more lettuce and other green weeds out of the greenhouse and fed all the birds. All the work the greenhouse has been is worth it if for no other reason than the joy of being swarmed by my mixed flock for a treat of greens in the middle of winter.
