Definitely I don't think it's a protein deficiency but a need for greens..Thanks for bringing that up. I haven’t this winter. Everything seemed fine before I had surgery and my focus was on getting through that. I counted on my husband and son to keep a good eye on things, but though they are good at maintaining things, they aren’t good at spotting problems. I have frozen peas and will thaw some and put them out for the ducks. Through the fall, I gave them everything that was in my vegetable garden that I knew wouldn’t harm them, but once I got hurt and the weather changed, I didn’t supplement their diet with greens because I didn’t have any coming out of the garden. We are now eating what I canned all summer. I didn’t even think about there being no scraps for the ducks! Oops!!
