I tried to ask for help in the "Broody Hen Thread" but my question just sort of got lost in the hundreds of posts (sigh).
Last year I had a hen (Buff Orp) go broody, gave her eggs I bought online, only one hatched. Another hen went broody (Australorp), same procedure but eggs from different seller/location, only one hatched. No more than 10-11 eggs under the hen each time. The first batch I don't remember how many were fertile and quit, or if I even checked. The second batch I did see quite a bit of development in some of the duds, but it seemed like they quit and various points in development.
SO: is it possible, being in high-elevation, dry Colorado that maybe the developing eggs needed more humidity later on? What other factors (besides the obvious shipped-egg variable) could be causing such low success?
I really didn't poke at the hens too much to candle, and had them completely separate from the rest of the flock to reduce stress or accidents. I could give more details, but I don't want to get carried away. Everything else with raising the two individual chicks went so well. I'd like to try it again, but need to get some ideas on what could be going wrong or how to hopefully improve my hatch rate to anything more than one! Any advice?
P.S. both chicks turned out to be hens (whew!) so statistically speaking if I try again I may only get 2 roos. And at almost $30 for eggs and shipping, each time, I don't want to spend that kind of money on boys I don't need!
