We have 5 Silver Laced Wyandotte hens. They are 23 weeks old and have just started to lay sporadically. Not all of them are laying yet. We think the majority of the eggs came from just one of the girls. My question is about their egg size. Right now the eggs are all about half the size that they should be. All of th eggs. Some are a little bigger than others, but they are all small. Can anybody tell me the time frame it will take for the eggs they produce to be full size? Thanks in adavance!
