I have a few Bantam girls (Frizzle Cochin, Dark Brahma, Silkie, Sultan, & Serama). The Frizzle laid her first egg yesterday-- just shy of 21 weeks old. Yay!! Questions: I have 1/2 a bag of chicken grower I've been feeding them, along with crushed oyster shells in a dish. Is this enough to keep them on until the bag's gone, or do I need to switch right now to layer feed? Will the Frizzle begin to lay an egg every day or so now? Or will it take a bit for her system to 'regulate' itself? The egg looks perfectly fine, if oval instead of 'egg-shaped'. Will it be OK to eat? Should the other girls begin to lay shortly? Or -- who knows?
