Question about foraging for rabbits. I fed my colony and tractored rabbits all spring and summer on a small amount of pellets, all the hay they wanted, and once a day I'd bring them an armful of forage. Fat happy fast growing rabbits. In previous years, I did pellets and hay alone, got happy rabbits but this year they seemed happier. Towards the end of summer I had trouble with some of the younger ones dying, both tractor and colony, at the same time, but not the caged rabbits, who I don't bring forage to. I thought I must have fed them something they shouldn't have done, but i hadn't changed anything, the same handful of species I'd been feeding all summer (goldenrod, ragweed, knapweed, thistle, nettle, dandelion, aster, bishopsweed). The only thing that had changed was the weather - also a new bag of food but same food, same supplier, no funny smells or difference in colour or consistency from the old.
It's the first year I've fed primarily forage and the first year I had a tractor. Wondering if the change in season meant a change in the plants I was feeding - I read somewhere that some of them can have more oxylates as fall comes on, maybe the balance got thrown off. So I've got two questions:
1.) Does anyone have a great site for this, i.e. don't feed X plant at Y time because of Z reason?
2.) I had left a meadow with some of the plants I'd been feeding wth the intention of pulling them in Oct / Nov / Dec before snow gets too deep. Considering the potential change in content, should I have harvested them in July or August and dried them, rather than leave them standing to harvest as needed?
