I'm scratching my head over this one - I have four pullets that are about 14 weeks. They happily run around their enclosure all day, and for awhile they'd go nuts over worms I'd help them find. Then one day, they turned up their little beaks at all the fat juicy worms I found for them. Yesterday I even saw one of the ladies (an Easter Egger) following a centipede intently, but made no attempt to move in for the kill. I was going to do some worm composting to raise some protein "on the hoof" for the girls, but now... On the other hand, they just discovered another section of their run that has fresh grass growing in it, and they went completely ape****. Now they've mowed down all the grass in the run! So I'm thinking they must know what they're doing, and they're getting enough protein and need some greenery, but still -- anybody else have fickle chickens?
