took another chicken to lab they told me to get wazine 17 for the round worms said they have it bad, they asked if we want to stay to see the lab work on this last one, which was still alive but could not stand t up. we said no thanks, so now we just have to wait to see what else they come up with, they were very nice and said they just came from geting another whole flock from someone in our town. they got them the same place we did as peeps, ( they said not to give any water in coop at night unless it is real hot, just give the water with meds, in the morning and leave it there for the day, they should drink it first thing in the morning, so out came the water from both coops. i sure hope this is it. he said as for the yolk thing nothing we can do, he did tell us about the lice. we asked him if we did right with how we used it, he told us to get that yard seven for gardens and vaseline, mix it together then put it on thier legs, we were told to put gas on the legs, did not like to do that so we just got a dust from ts and they like rolling in that
