Have to disagree with what they told you. It's good, but...Chicken poop is one of the hottest fertilizers out there. Not a good thing. Unless fully composted it can burn and kill the seedlings. Find somebody that keeps rabbits and offer to clean it up for them. Rabbit poop is the best and can go directly to the soil at planting time. My second choice, for soil building purposes, would be sheep.
Best choices for chicken are to add it to compost and spread it sparingly after a year OR buy it fully composted. I get it composted at a value of 5-4-3 from Fedco in Maine, $25 for 40lbs. when I run out of my own.
I also compost with worms in my basement year-round. Worm poop can be added to seed trays at 10% for a noticeable boost in vigor. can be spread at apx. the same rate for in row plantings. And it costs nothing to feed worms leftover coffee grounds and shredded junk mail. Leftover plain pasta with no sauce is like candy to them.
