My 2 Ameraucana chicks are 4 days old. Now both of them are chirping like CRAZY every time I leave the room. Their brooder is clean and 82 degrees (any warmer and they are sleeping away from the heat), they have food and water. As soon as they hear my voice, they charge towards me and try to jump/fly over the brooder wall to get at me. If I sit there and put my hand in the brooder and talk to them or hold them, they go to sleep or just hang out happily on my hand or lap. They freak out as soon as I put them back in their brooder and have to walk away, and it goes on and on. They were on the carpet yesterday beside me, and I got up and walked a few steps...and they ran full speed after me. Is this normal chick behaviour?! I've never owned chicks this young....the youngest prior to these guys were 2 weeks old and didn't do this. We are getting 2 four day old Icelandic chicks today to add in with the Ameraucana's....maybe that will help?
