My chickens LOVE to scratch in the hay for seeds--wanna try black oil sunflower in this next real cold snap over the next few days--kind of like chicken aerobics. The shred up that cabbage and collard in no time too.I won't let my girls free range.unless my DH and i stay on hawk patrol with them.so we have constructed a large run.half the run is sheltered from rain and wind.the other half has wire on the top to protect them from predators.two weeks ago we had some very cold temperatures.their was no straw to be found.we purchased bales of hay.i took flakes of hay and put it threw out their sheltered runs.those girls had a scratching fun time looking for seed that had fallen out of the hay.I also took scratch feed and toss it in the hay.keeps them busy and good exercise for them..and also keeps them warm.treats are meal worms and alfalfa sprouts and cabbage.the other evening I let them out within ten minutes they went back into their run.and started searching and scratching in the hay for seeds and scratch.
I do not free range either--we have LOTS of flying predators--maybe the roo would hustle them under the shelter but if any one of they became a "sitting Duck--err Chick" I would feel horrible. Will increase the covered yard area in the next few weeks with bird netting. I know they'll love it and I will have some sort of peace of mind--until a hawk gets caught in the netting probably.
