Ok quick question. I have 20 chicks 6 weeks old and 8 guineas all on starter feed heavy with protein for growth. Today I bought 3 sebright banty chicks and I was told they were aprox. 25 weeks old. 1 rooster and 2 girls. I never had bantys and im amazed hiw small they are and just cant fathom them being 25 weeks old but the seller said they were and is very experienced and i am taking him at his word. The rooster crows but the hens have not yet laid an egg. The seller said any week now I should see some eggs from the 2 banty sebright hens. My question is being that my 20 chicks will be on starter feed for a while longer, should I buy seperate layer feed for the sebright bantys? I am excited for them to start laying and was wondering if they are of age and i switch the feed to layer will this perhaps get them laying? Would you feed the 3 older birds layer while all the rest stay on starter? Thanks to anyone who chimes in.
