I have four chickens—a buff orpington, rhode island red, a silver-laced wyandotte and a gold-laced wyandotte. They're all healthy and have plenty of space to roam, plenty of food (organic layer feed, scratch, vegetable scraps and some meal worm treats among other yummy things). We got them in early April of 2016 as pullets (between 8-12 weeks respectively) The rhode island red and buff have been laying since mid-summer and are pretty regular, usually 1-2 per day depending on the daylight hours. We're in Colorado so the days are short here in the winter. But the wyandottes are STILL not laying. They are definitely (or seem to be) full grown and of laying age, but we're not getting a single egg from them. I love them and they're beautiful birds but I can't keep paying for their organic feed and treats with no eggs in return. Any thoughts on what might be up with them or how to get them going? We've placed golf balls in the nesting box and with the other two laying figured it would only be a matter of time, but no dice. Help please!
