I have 7 hens and 6 cornish cross chicks that are 3 weeks old. I see worms in the poop tray, clear and about 1/2" long, don't really know what kind. Both mom hens are fiercely protecting the babies. They were sitting on eggs that I figured were not fertile, so I put chicks under them. I had someone who wanted all the chickens and thought, oh, I'll have chicks to butcher at the time he comes to get the adults, but now the guy changed his mind. I'm traveling a lot for work and plan to get rid of all the chickens anyway, so now my plan is to butcher them all when the chicks reach size. Should I treat them even if I'll be butchering soon? If I treat, do the chicks need it too? I have fenbendazole liquid. If I treat tonight and then again in 10 days, I've only got another 10 days before butcher time, if cornish cross are ready at 6 weeks. I'm not concerned about residue in the meat or eggs I get before then, just want guidance. The older ones are all over 3 years old, several are more like 7, and I'll probably just use them for broth. Would you treat only the adults and not the chicks or would the chicks not make weight unless treated? I'm just so ready to be done but don't want any of them to suffer. Also, I'm not too sure how old the chicks are, really, probably several days old when I bought them, not that a few days really matters. Any thoughts? Thanks.
