We just got our babies yesterday around lunch. Everything was fine until this evening. The chicks started pecking at each others vents (bottoms) and tearing them open. I am freaked out. I have no idea what to do. We have been cleaning their bottoms of any built up poop and unclogged one vent already. I am keeping them clean and dry. I have separated the two that were wounded, cleaned their wounds, and am hoping for the best. They are currently in a bathroom that we don't use. The bathtub drain has been blocked off, and there is litter on the floor of the tub. They have access to plenty of food and water. We were using a regular heat lamp until tonight and when this started happening I got online to try to find something that would help. I couldn't find much. Just that the red heat lamp bulb may help. So, I sent my husband to get one. I also read that they may be overcrowded or too hot. I moved the heat lamp up, farther away from them. And they have the whole bathtub for 9 one week old chicks... They seem to have plenty of room... I really need help on this if anyone has any suggestions. Thank you.
