I have about 10 chickens (mostly different coloured Orpingtons) who range from 7-9 months and NONE of them have layed an egg yet! I have been watching since about the end of September and by now I thought I’d have something. All of them have red little combs and wattles. They get plenty of fresh water, the have a clean roomy coop and they free range late in the afternoon(so I am sure they aren’t laying somewhere else) They are on layer feed and all seem healthy and happy....I feel like I have a bunch of spoiled free loaders! What is going on?
