I'm new to the whole chicken thing, but have been around them for awhile now. Decided to get my own and so far they've been fun and quite adorable. I'm having an issue though that one of my baby chicks is becoming more aggressive towards the other (I only have 2 pullets... hopefully). There's plenty of warmth, chick starter and water. At three weeks I'm starting to wonder if the cause is: 1. It's a rooster 2. Space 3. It needs to be separated 4. It needs attention ?? 5. Only 2 in the group The odd thing is.. I was having to clean the other for possible pasting. The issue has been resolved but when I would take the other chick out, the naughty little chick would chirp extremely loud until I was done cleaning and placed its buddy back in their living quarters. I don't want to stress the little bugger, but I'm nervous of the aggression. I see the naughty chick running from one side of the bin to the other to almost 'cut off' its buddy. Also, they're kept behind closed doors due to resident cats. I'm in the room frequently to give them fresh water and simply watch/socialize them. When I'm not in the room I'll hear a sudden loud chirp and I know the little jerk is at it. Once I open the door they're peaceful. Maybe they're tired of their surroundings? I'm nervous to put them outside in a small coop because I'm sure they'll attract raccoons eventually... (I've seen racs get into coops before... not pretty). Any advice would be super appreciated.
