chickens r life
Songster
There is no chance it is a rooster. By this age they would have had pointed saddle and hackle feathers and male sickles. I wonder if she has worms. Hens will stop laying and their combs will turn paler if they have enough of them. Mites or lice can also cause laying problems if infested.
PrettySpeckleds said that she had not laid an egg for her previous owner either... Could she have had worms/mites for that long? To me it seems extremely unlikely as the hen would have died if she had worms/lice/mites for 2 years...
