When I moved some concrete stones from under their waterer, I found a ton of earthworms of all sizes. Wow! I thought--what a treat. So I called them over. Only the BA (who is the best forager ever) took notice and gobbled them all up. The other 3 wandered over, looked, and then wandered away.
They'll eat grapes if I cut them in half or squish them. They're not crazy about lettuce greens or cabbage, tho' shredding the cabbage helps. But then I found out the dogs were running out when I wasn't looking and eating the cabbage--no wonder they stunk up the bedroom that night! The dogs will eat things they'd never even considered before, fopr no other reason than to keep those @!#%$^! chickens from getting it!
