Thanks on the info Dan!
Well what you both say is true. Their nesting habit is a pain, l find lots of egg clusters out in the bushes, they just lay a dozzen egs and abandon the nest later. Luckly the shell is extremely tough and the eggs seem to have wery long shelf life so l usualy just collect the eggs from the abandoned clusters and do the water boilency test prior to use to check they are good.
Here people with a flock of foreging chickhens throw in a pair of guineas for hawk and eagle protection. l usualy have one or two alarms per day so its bearable. Althugh its true, once they start making noise, a chain reaction starts with all my birds singing in a not so pleasant quoir turkey, peacock, rooster… its fun thugh.
I put guinea hen eggs under a Turkish hen (pigeon sized hens, exelent incubators) they hached but only lived a day, some animal must of eaten them. I suspect the hen with the chicks came looking for food in the pig box…
