This is our first time keeping chickens and we got 5 chicks from a local breeder. We live in the suburbs and can't have any roosters so we paid extra to have the breeder vent sex all our chickens.
About 8 weeks later one of them was clearly a rooster (reddening comb) and we had to return them and trade them in for a new hen around the same age.
12 weeks in and two more of our chickens were showing very clear signs of being roosters (i had my suspicions for awhile but could never quite be sure). The breeder didn't have any more the same age so we had to trade them in for two 6 week old hens. Of course now our chickens are upset and we are having to integrate them slowly.
It's now 14 weeks in and one of our last two original chickens crowed! For the past few days we haven't heard them crow again and I've been really hoping it was just due to the pecking order being disrupted and/or taking over as a "rooster" but now their posture/appearance is telling me they might also be a rooster:

So at this point we are very reasonably upset as we spent all this time bonding with our chickens, buying food and getting excited for eggs and now we probably only have one of our original chickens left (which is a black sex link so SURELY they cannot be a rooster...) and the breeder only has younger chickens left meaning we would only have one actual egg layer left (our other one the same age is a bantam so they will lay smaller eggs...)
4/5 sexed chickens turning out to be roosters seems ridiculous but the lady that sold us the chickens is very nice and knowledgeable so I think we just got extremely unlucky. It just feels hard to bond with chickens at all now considering our last original hen is very unfriendly and hates being held at all.
Has anyone else been this unlucky?
