I have a one year old buff orphington who had had a hidden nest for a while. For the last three days I have kept her in the coop until she lays and then let her out. Tonight she did not come back to the coop. She has not been seen since about 11 am. I have 6 other grown chickens, 1 rooster and 22 chicks under 15 weeks old. They are all back in the coop after free ranging for the day. My question is should I let my chickens out tomorrow or leave them in the coop? Is it likely she was snatched by a predator in broad daylight who will be back to get some more of my chickens or did I push her into going broody by keeping her from laying in her nest for 3 days?
