I have a glassed in back porch room that I am currently using as a nursery with several chicks of various ages. I did have a mama hen (bantam silver laced cochin) in there with her only chick for awhile, but I had to keep throwing them out during the day to free range because she was aggressive towards the other chicks. Anywho, they have been going out for over a week now every day with no issues. They both stick around the yard, with the baby staying very close to the mama hen at all times. At dusk, she brings her chick back to the porch door.. well, next to the porch door is a fenced in spot where trash cans are supposed to go. She huddles down in there with the baby chick and I go out every night between 8-9pm and bring them both in to sleep on the porch. Well, last night the only one there was the mama hen. There was no baby under her and no sign of it anywhere. I have looked over as much as I can of my yard and my neighbors yard with no luck. I'm not even hearing a distress call from the baby. The mama hen has given up looking for it and rejoined the rest of the flock free ranging today. My question is.. what on earth could've possibly happened to it!? There is no clues. No feathers. Nothing at all. The mama and her chick always stay near the house, they are either under my front porch or in the bushes. I was thinking hawk or crow.. but there is always cover because we have a lot of shrubs and trees surrounding the house. Then I was thinking snake.. but I just don't know how that could've possibly happened because the mama hen is incredibly protective. She is extremely aggressive if she feels her chick is being threatened. I have three outdoor cats but they are used to chickens and this chick has been outside with them for over a week now and they haven't shown any interest whatsoever. We have had many predator problems before.. but just not like this and not during the day. I usually have issues with raccoons and foxes at night/early morning and I feel that even if it was a day time attack by a raccoon or a fox, it would've gotten the mama hen first. PS: The baby chick was not a bantam. It's father was a bantam and mother was standard size. The chick was standard size too. It was over 2 weeks old, closer to 3 weeks. Fairly decent sized little chick. Fully feathered. Not just a little peeper.
