Bumpa-bits can be purchased from Jim Rea

The 35mm bits I installed on the Fearsome Four seem to be doing the job. As I expected, they are all so darned ornery they had no trouble adjusting to the longer bits. I'm glad now that I had the choice. Jim Rea sells the 30mm length, which is a better fit for most standard chickens.
Both devices are installed with snap-ring pliers, which work the opposite of regular pliers.
Yes, I've allowed one of the Fearsome Four, my Speckled Sussex Linda to sit and brood eggs twice. She is currently broody for the eleventh time. She's a cereal broody hen. If I'd let her sit eggs every time she's been broody, I'd have around 75 extra chickens by now.
