BOSS is great to feed to chickens and to horses even. We feed the horses whole oats and BOSS and the chickens eat the undigested seeds from the manure- effectively spreading it for us without us ever having to hook the drag up to the tractor. Plus, come the summer, the manure pile looks like a sunflower garden. I get mine at Lowes and it germinates really well.
Yeah - I'm feeding a handful of BOSS seeds to my patient every day or so too (whenever she runs out). Hopefully that will help her out with the healing/feather regrowth. At this point she's healing amazingly well - thinking of renaming her Captain Jackie Harkness. (Yes, I'm a nerd). More worried about her bum getting cold since she's got no feathers on it when I put her out with the other survivors than them picking at it. Think I'll put her in with the new chickies instead when the time comes. That way she'll have an extra few weeks to regrow feathers over the area to help insulate her. Doubt she'd let the wee ones pick at her since she's got a good two months on them age wise.
