I'm always happy to see pigs born at this time of year. It's not great weather wise (although this years very, very mild winter is very nice) but it's great for the market. Spring pigs, particulary those born in january and february, are usually in short supply, and are desired as show pigs and fair pigs.
Right now I'm carrying 120 piglets ranging in age from 1 day to 4 weeks. I run this sort of schitzophrenic path when I have this many piglets -- "what am I going to do with all of them", and then I'll have a good sales weekend, and sell 60 pigs, and then I switch to "I'm out of piglets! I need more".
Kinda like that stress. Beats the heck out of staring at the back of a car in traffic.
