I have dealt with Meyer for years and not had any problems but I always get chicks.
As one poster stated it is just good animal husbandry to deworm your birds regardless if any birds had previously been there. Round worms are carried by many species of mammals so I am sure the pullets picked them up easily enough at their new home. They are in the soil and chickens peck the ground constantly. Roundworms also are fast growers in the body of an animal and the warmer the better.
It seems to me that this new owner does not have much of an idea of poultry farming. If I were getting into something as huge as that many birds and spending obviously a lot of money, I would certainly do my homework. Deworming is a monthly ritual at my farm and with as many pullets as that it should have been for them, as well. Anyone expecting to just purchase birds and make some money without constant care and maintenance will be sadly disappointed in the outcome.
I do not blame Meyer one bit for their reaction. I have sold birds and had people come back months later to complain about something as simple as their neglect of the animals. That is pretty much like buying a new car and then complaining once it runs out of gas. The new owner has to take care of their purchase.
At my peak this summer I had around 700 poultry here on my farm but each one is picked up and weighed, checked for wounds, exteranl parasites and dewormed, not to mention every 3 months a stool sample is taken in from where they roost at night to the vet to check for internal parasites. I don't want my investment to go down the drain.
