I can't figure out what is happening to my guineas, and thought I could get some help. My guineas are completely free range during the day. My main reason for keeping guineas is tick control, and I am happy with their work. At night, they come into the coop and the door is shut. I keep them locked up for eight weeks so they know where home is. I have found no evidence of predators accessing the coop. We have a not-very-busy side road in front, neighbor to the left, woods in the back, and field on the right. Only one guinea was hit on the road. Another guinea was attacked by a hawk. I also lost three guineas to gorging themselves on freshly mowed grass. Thinking it was bird flu, I called my state Ag Dept and they took a bird and examined it. They found the grass lodged in it's crop. Last summer I started with 16 guineas and went into fall with only 3 males. We butchered them, and moved the 15 new guineas I bought as chicks To replenish the flock into the coop. Right now, it's only the end of May and I am down to 10. I did make one change this year and now they start free ranging at 1:30 pm. I was hoping it would force the females to lay in the coop, because I thought they might be trying to stay out to sit on nests. Most of the day they hang around my yard and the neighbor's (who is cool with them). Any suggestions would be appreciated.
