"The ones who are selling have put the price up. Generally for a big bale of hay you pay 10 to 12 pounds under normal circumstances. Now I heard 25 to 30 pounds. We can't afford to pay that for hay," he added.
A field in Roberts farm was under 20 feet (6 m) of water at one stage and the top of a 5-foot 6-inch gate has only just become visible as the waters begin to recede, he said.
Halling's farm has lost its supply of mains water and has been relying on water trucked in by the National Farmers Union.
"People have been very good. I even had a lady in the village ring up offering me her swimming pool water to help the animals. It touches a bit at times," Halling said.
In nearby Upton-upon-Severn, mobile homes in a park near the river are largely submerged and two rugby goalposts stand tall in the middle of a newly formed lake.
The community temporarily became an island as floods swept across the region this week.
Rooker also travelled on a tractor trailer over flooded fields to visit the dairy farm of Trevor Jaynes, a few miles away in Longdon.
Jaynes said there had been no milk collections for several days this week and he had poured 3,500 litres of milk down the drain.
He has had to purchase brewers' grain this week to feed his cows and expects to lose crops which remain under water.
"They are starting to rot already," he said.
Jaynes runs the farm with his sons Terry and Tim. The family have been using a kayak this week to tour the farm.
Chris Simpson, an inspector with the Royal Society for the Prevention of Cruelty to Animals (RSPCA), said the floods had put many animals in danger.
"We are looking at something over 5,000 animals that we have helped to rescue. Yesterday we rescued a cat that had been trapped in a hayloft since Saturday and the only way we could get to it was by boat," he said.
