we just found one of our chickens trapped under an overtuened PLASTIC flower pot. she has been gone since FEBRUARY 25, & my hubby found her today because we are planting in our pots. we thought she had been snatched by a bird of prey, but here she is!!! i have never heard of such a thing, but moving forward we will be very careful w/ these & other things that can be turned over & trap little animals. i feel so awfu! other than weight loss & messed up feathers, she's actually ok.
