It seems like we have a reliable brooder in Buffy. After Lucky hatched, Buffy stopped brooding, of course, and didn’t continue laying. She was busy being a Mom. That was months ago, and Lucky is his (? – we think) own chicken now, with no real need for constant mothering.
Because she’s a bantam Easter Egger, it’s easy to tell if Buffy is laying or not — hers are the only small blueish eggs we get. She started about 10-12 days ago, and yesterday seems to have gone broody again. Interestingly, she laid just about one clutch’s worth of eggs after Lucky went out on his own before going into Mom-mode again.
