Drawing becomes an inevitable activity for our preschoolers at this age. Be it at home or in school, children aged 3 to 4 are constantly drawing. Of course, they have progressed through the scribbling stage where their drawings become more recognizable.
Which parts are missing from a dead bird can help you identify the culprit. A chicken found next to a fence or in a pen with its head missing was likely the victim of a raccoon that reached in, grabbed the bird, and pulled its head through the wire. When you find a bird dead inside a chicken pen and run (or a coop, for that matter) with its head and crop missing, your visitor was a raccoon. If the head and back of the neck are missing, suspect a weasel or mink.
The herbicide paraquat, when sprayed onto bird eggs, causes growth abnormalities in embryos and reduces the number of chicks that hatch successfully, but most herbicides do not directly cause much harm to birds. Herbicides may endanger bird populations by reducing their habitat.
