Hi! So I have just had some of my chickens, one a Polish, two bantams. They were in a cage that was supposed to be proofed for things getting in. Something got them in the daytime, because at night they are completely sealed up. During the day we let them out and they are still inside the cage, it is a metal cage and originally had no roof, but we put chicken wire and some metal roofing over it to cover them. The cage metal is not entirely small holes, but holes small enough that animals cannot fit through them, but somehow, something got my two bantam hens, and my polish. Could anyone please help me to figure out what could have gotten in, what type of predator, and maybe how it got in? I'm devastated, they were my babies and I want to be able to catch whatever got them. Any help is greatly appreciated, thank you.
