those are black vulture and they will kill live animal , now turkey vulture are shy and will not go ater anything moving or alive,
redtail hawks don't normal go after birds, they will but more like small animal
no need to check air cell now...just the three time on that chart.
Little Giant incubators
accurite i got @ Wal Mart reads temp. and humidity, also high and low of both so you know how high or low was thru the hatch,
checking the air cell is the best, i have two new accurite one read 26% the other47% humidity. lot of hatch problems are people don't know true temp. or humidity are in the incubator...i have great result at 47%.
sound like you will have a good hatch......LG are hard to hatch in, plus...
