I have 3 barred rocks and 3 buff orpingtons and they have been laying since August. They are about 40 weeks. I also have a pair of mottled houdan that are 38 weeks and she has not been laying at all. He has been breeding her for months, but I have not seen an egg anywhere. I even kept all of them in the coop for like 3 days (it was rainy) and still no egg from her. At 38 weeks she should be laying by now right? Would the rooster try to breed her even if she wasn't close to laying? He sticks with her (the other ladies won't let him get close to them). I also have a pair of silkies that are 36 weeks and she too has not laid an egg. I had another silkie hen (she died ) and neither of them has laid an egg. I have 9 guinea who are 32 weeks and none of them are laying. Is it simply because of the winter or do you think they are hiding their eggs somewhere? I have checked all the places I could think they would be laying them. No one has disappeared for any length of time either. They all stay on the porch ( I will be glad when bugs are out again and they will forage more). I really do not think that they are laying somewhere else. There are plenty of nest boxes (the silkies used to sleep in the nest box, they won't roost even though a low roost is provided). If they don't start laying by spring they are either going on the dinner table or on down the road. Any advice is greatly appreciated. I would really like to incubate some Houdan eggs if I can get her laying. How long does it usually take these birds to start laying.
