Good evening, all. I have a question for all you BYCers. I have 2 hens who are BR mix, and 5 RIR pullets. Now, the pullets were hatched on Jun 4 from hatchery, and the BRs were hatched at a local farm around beginning of March. Oh, we also have 2 BR mix roos. My BR girls have bright red wattles and combs, and the RIR's are getting there. The two roos have been mating with the two BR hens for at least a couple months. I was feeding them a mix of cracked corn and starter mix while they were younger, then switched to a mix of cracked corn and layer pellets about 3 months ago. As of the middle of last month, I switched to 100 % layer pellets. They get veggie food scraps as it's available. We live on the central coast of Maine, so daylight and temps are going down. They have an enclosed nesting box with a curtain over the door, with two plastic Easter eggs nestled in the straw. My wife told me this evening that her coworker, who we sold eight RIR pullets from the shipment of 25, says that the RIRs have started laying as of last weekend. So, my question is this: I have seen posts saying that 16% layer feed should be given.....but I think that's for people giving more scratch than feed to their chickens. Should I not be giving my chickens straight layer pellets, and add some cracked corn? The last time we fed the cracked corn mix with the pellets....they were only going for the cracked corn....so we switched to 100 % feed. Could the diet I am providing them be the cause of their delaying to lay? Also, do I still need to provide a container of oyster shells or egg shells for calcium? Thank you in advance for your answers.
