Well we are encountering our first problems with our single baby. Its starting to get cold at night and he's all by himself. We have in the garage so its not as cold as outside and at 8 weeks he should have most of his feathers. We're still awhile away from merging him into the coop with the others. Well there's only 2 others and they're roosters and we're pretty certain this one is a girl even though I call him he. So how cold can it get while he is by himself? I'm assuming it would be worse to put him back in the house since eventually he will have to live outside. We're only talking lows in the 50's right now, but its been damp and cold.
