We have 3 hens, roughly 8 months old ... and none of them are laying. Near as we know, the hens hatched in mid-April. (Were expecting all to be speckled sussex, but started asking questions near end of June when it was clear one was not like the others.) The speckled sussex hen in the front seems less mature than the other 2 from a size-and-color-of-comb aspect. Closer pictures of the two more 'mature' appearing hens are below. The hens free range, but there is no evidence of nests--plus, they've been confined to the coop for days on end without any eggs. No apparent interest in nesting box, even with a couple golf balls in it, not squatting, no egg song (really, only the bsl talks, but she's vocal enough for all 3 plus several more). Feed is Purina Layena, along with plenty of corn and sunflower seeds snacks, plus whatever they eat in the yard and woods. Not interested in oyster shells. All hens seem healthy and fine ... just not interested in laying eggs. Any thoughts? Suggestions? I will appreciate any input anyone can provide. Thanks!!
