All of my research on Catts and their crosses have said specifically that "too much Nitrogen suppresses blooming."
Chicken poop has a high N content so that may be your blast problem. Traditionally it takes 6 months to compost it. The horse manure at our barn takes 6-8 months to compost and that is with watering and turning it.
I'm currently giving mine a low N content fertilizer because I should be getting some blooms (fingers crossed) late this summer.
