Example: We guarantee on a 100 paid pullet order that you will receive at least 90 pullets (assuming all the chicks survived to be counted). If we make an error and we did not live up to our stated guarantee, we will refund the pullet purchase price on under 90%. In other words, if you have over 10% that are roosters in your pullet order (including any extras that were sent with your order) we should be able to refund at pullet price over the 10%. Claims must be sent directly to us when chicks are not more than 12 weeks old. We have one of the best rated and multiple genders selecting methods in the industry, however, still it is only about 90% accurate and it is not a perfect science. It is recommended that you give some thought to the possibility of receiving 10% males and what you would need to do under the circumstance. We do not have any guarantees on percentages on males or females for not sexed/straight run chicks. We do not offer sexing on all of the breeds we sell, for these breeds it is either too hard on them or the professional sexers’ accuracy is not good enough and could cause customer dissatisfaction.
