Countryfile star Adam Henson has had his concerns eased after a "terrible" period for some of his livestock.
The farming presenter shared an update on his lambs after his farm faced a "hideous" drought last year.
In one segment during this Sunday's edition of the BBC programme, Adam began: "Improving biodiversity is only one part of the challenge on the farm. We're also trying to breed livestock that can thrive with fewer inputs."
He explained: "These are our rams, and last year, we set off with a bit of an experiment, we brought in two new breeds, the Romneys, the white-faced ones, we got two mature rams in there, and they were to breed replacements, so they go on to our yews and we keep their daughters.
"They came from a flock where they'd been concentrating on working out that those lambs need less wormers that you'd put into the gut of the animal to kill the stomach worms. They're expensive to use but they are also a little bit damaging to the environment.
"The other rams over there are the Hampshire Downs, and for the Hampshire, it is all about meat production, but for them, last year's lambs, it was a difficult trial, because we had a terrible drought with very little grass.
"This year, we've got to work out whether they're producing the quality of lamb we need to be able to send into the markets."
Adam went on to share how the Hampshire Downs had been brought in to bring lambs that grow well on just their mother's milk and grass, removing the need for manufactured feeds, lowering costs and the environmental impact.
After last year's drought proved difficult, Adam and his livestock manager Sam are looking at this year's results.
Adam said to Sam: "Last year, we had that hideous drought, I was feeding hard food to the yews and lambs which is very unusual, it got quite difficult to judge."
Sam replied: "They really go backwards, it was a tough time, there was nothing we could do."
He added: "It was a tough time so fingers crossed, we have a fairly stable year weather wise, that would be great, so they'll thrive."
Remarking on some of the sheep, Adam commented how one set of twins were looking "tremendous", while Sam said he was "really impressed".
"They've absolutely grown over the last few weeks," he added, saying the Hampshires were "beautiful to look at and really lovely to work with".
Adam concluded: "I'm glad they're looking well, perfect!"
Elsewhere in the programme, Adam welcomed a new addition to his farm, a gorgeous little pony.
"She's huge!" Adam said as he saw the Suffolk Punch for the first time, a rare breed of horse.
"Every foal that we can get that's fit and healthy is very, very valuable to the breed," he explained.
"She's got such long legs and she's only 17 days old!"
He added: "Aren't you beautiful? It's alright, your mummy is nearly there!"
Adam commented on the "beautiful" bond between mother and foal, saying: "She seems pretty relaxed," before sharing the foal's new name, Hera.
He said: "Hera is a Greek Goddess and lady of protection, so I need to do a bit of work with her, she's still quite nervous. It's lovely to have her... little Hera there, she'll be a superstar."
