I'm in zone 4 and with the winter season already here, I'm running out of things to prune in my greenhouse to supplement my 30 chickens and 15 ducks with healthy snacks.... what can I grow abundantly and speedily inside my comparatively smaller indoor greenhouse window that I can cut and come again for treats each day?.....I did fodder trays last year but it is so stinky
and require daily rotation/reseeding of trays
....any suggestions?
