Of the 7 chicks my grandaughter brought home from 4-H, 3 are cockerals! Our town ordinance only allows 1 rooster and neighbors on both sides have complained about the crowing (they are 7 mos old). Well of course we love them too much to find new homes where they of course will be "euthanized" because inevitably they won't fit in and people joke about the stew pot (the story I hear the majority of the time). Not for my babies, no thank you. After much searching I found a delightful avian veterinarian that is willing to work with me to neuter my most aggressive boy (he's rough on the girls and his brother). The removal of the testes may make a difference on this behavior; of course it may not. I read the summary of a UK vet who did one and the rooster crows much less and is docile. Vets are not schooled in neutering of roosters in school but my vet (Weymouth Massachusetts) has operated in birds abdomens and pelvises, uses a bird anesthesia machine (not a human one), and has 2 certified anesthesia techs (which are rare). One of my hens is going too in case blood is needed; in that case she will be sedated and blood removed with a syringe. He has done tons of research to prep for this surgery for my boy and is kind and enthusiastic towards this whole project and us. Scheduled for Veterans Day 2019. 10% chance of not making it. Please pray for my Checkers!
