I have a mixed flock, some Japanese, some Cochins, RIR's Buff Orps, and EE's, among others. I get nice sized eggs from my RIRs and EE's, who are older, but my Cochins, (6 months old) seem to only lay little eggs, not much bigger than the Japanese! They have been laying for about 2 weeks +/-. Will they always stay these little 'practice' eggs, or can I hope for bigger? We feed egg layer crumble, and they free range everyday. Below is a photo of the eggs, from left to right there is.... 2 RIRs, EE, 2 Cochin, Japanese, and the odd round one I think is either from the Golden Campine, or the Crevacoer. (but thats just a guess based on bird size.) Do buff Orps lay small eggs?
