We have a 90% Sex Accuracy Guarantee, that guarantees that your order should be at least 90% accurate in the sex option you had selected. If the error is not over 10% we would not be able to credit your account due to the reality that even at a day of age a chick may be mis-sexed. This error is not common to occur but we will certainly reimburse you for the cost of the female you were suppose to receive, if you had received a male in it's place (if the ratio would meet the guarantee percentage).
What do you do when you have a suspected Rooster?
We ask that you wait until the bird is 10-18 weeks of age and if possible at that time we will request that you send a picture of the suspected rooster, not only for our records but so we can properly identify it as well.
Under 10 weeks of age:
"It's comb is larger than the others and is more bossy/dominant"
"I think one of them is trying to crow":
It would be completely understandable to suspect a rooster if one or both of those statements apply to your birds. We are happy to discuss the possibilities but wanted to let you know as well that even if you would order all the same breed: it is possible for a few to mature more quickly; causing a more noticeable comb even as females.
Also, that in a flock of all females, those that mature more quickly than other may start to display dominant traits and even try to crow. With that said when chicks are under 10 weeks of age, the wait time is highly recommended to be certain we would credit you appropriately because it is possible for a rooster to mature more slowly than some hens in some cases of certain breeds.
Below is an example of things to look for in a Rooster:
Note that saddle and hackle feathers are very pointed. The Sickle Feather is a long defined feathering. The Easter Egger is a great example of the fact that the combs are not always the most telling characteristic of a Rooster.
