The last couple of weeks I've had a problem with something getting my eggs, leaving shells and only eating the inside of them and getting my baby chicks. Whatever this is, is not bothering the big chickens. But it's taking the babies from their moms. I had three chicks that were about a month old that had been hatched in an incubator and the hens weren't real accepting of them so I had them in a small area that would keep them safe, I thought. This little pen within a pen was made with metal grating that I can barely get a finger through, the top had chicken wire, everything was attached very firmly. I put a tarp over part of it to keep them warm, went out to check and my chicks are gone, though nothing has been disturbed, not even the tarp. All three chicks gone, only a few feathers and guts. I'm at a loss, I have lost 10 chicks, not including the eggs that were ready to hatch. Any ideas ??? Oh, also found one chick that had been torn to pieces but not eaten.
