Kiki, that has to be the saddest coco liner I've ever seen.
Define "quickly." Coco liners do have a limited lifespan and have to be replaced, but I can get five years or so out of them, unless the birds decide to demolish one for nesting material. Granted, I have the benefit of extremely mild weather (one could even say a lack of weather).
I have found that starting with a good liner is the key. I think all of my current ones are Panacea and the fibers start out stuck together with a natural latex. I've had other brands without the latex that only lasted one season. Eventually the latex breaks down and the liner gets progressively fuzzier.
This pic sort of shows Panacea liners aging. The liner on the upper left was new last summer. The next one, with the very spotted begonia ("Matchmaker," one of my favorites) is getting ratty and is probably about four years old. The next two are probably on their third summer, except the juncos were picking at the dark begonia's liner to get nesting material. The juncos have had three successful broods each summer for the last three years in one or the other of the begonia baskets.
