Hello, I have 2 hens (full-size) and a Bantam Rooster. They are all 6 mos old. They have been together since birth. I got them at the end of June. They have a small wooden coop and I put it by my back garage door with a Sunbrella tent over it for the winter. I keep them very clean and well-fed and watered. The 2 chickens have been laying one egg each nearly every day since Dec 10. I let them out free in the yard an hour or more every day if it isn't too cold and I keep an eye on them. They don't wander too far. So, they are well-loved. They stay outside all night, but when it is very cold, I put them in a dog crate in my garage with food and water. That happened last night as it has been about 0 degrees here and it is only 5 degrees right now at 11 am. That's the background info. So, I let them out this morning and all was OK. I just went out to gather the eggs and give them more water (because it freezes, I change it every couple of hours) and my little Bantam has a bleeding comb (the thing on top of his head). It even looks like one bump was bitten off. I wrapped him in a towel and brought him inside to wipe off the blood and I put fresh shavings in the crate, food, and water. He is now in there alone, but he's crowing because he hates to be apart from the girls. What should I do for him? Do I need to keep him separate and for how long? What happened to his comb? No evidence of a predator getting in, but it wouldn't be impossible- HELP!!! I love my little chickies.
