I fully expect to get yelled at here, but in Gerald's defense, I have a similar philosophy when it comes to worming my Peas. "If it ain't broke.......don't fix it", in my defense please remember I have a hen that is coming 22, and a lot of my main breeders are 10+ to 15+ years now, and I've had these birds since they were young/chicks so I'm not just letting birds die and replacing them. If the birds look healthy, act healthy, and are eating, drinking and pooping normally I put the wormer in the water. I do use double the dose Gerald mentioned for Safeguard in water. I see no reason to stress a healthy bird. Now... if I see any sign that a bird is acting "off", the first thing I do is catch it and start the oral worming for 5 days. Also, anytime I have to catch one for any reason, nail trimming, tail brushing, changing pens, first aid, etc.... they also get an oral shot of safeguard. Fecal samples here have come up positive for small amounts of capillaria, coccidia, and round worm, and we are very diligent about oral dosing all young birds under a year old, but the adults seem to be able to handle it with this routine. Doesn't mean it will work for everyone, but again, I think a lot of Pea keeping involves finding what works for YOU, and watching your birds diligently. With my cancer treatment last summer, I wasn't able to keep as close an eye on them as I like and as a result I lost 2 hens.
