I noticed an egg outside in my pen of bantam buffs today. They are all this year's hatch and the oldest ones are 21 weeks old. That's pretty good, since hybrid layers have an expected Point of Lay (POL) of 18 weeks. When I checked in the coop I found two more eggs. One is a bit greenish. Then I checked in the bantam silver's coop and found 6 tiny blue eggs.
I found some in the Lavender Bantam pen yesterday, which the majority of them came from you so I expect those are the ones laying.
My oldest Ameraucana pullets were hatched just before April 1st, so I'll be waiting awhile. But I donated eggs to hatch for 4-H kids in several counties locally last December and January. Yesterday, a Wheaten bantam pullet took best of show at the Trempealeau County Fair. Don Karasek judged. The show had quite a few top quality birds. Same location as our local CRPC show in June. Reserve of show went to a Belgian D'Anvers pullet.
