Not sure if i should have just asked for the other person to elaborate a bit more but thought it may be a good question to ask since there may be a lot of new-to-chick-raising people on here like myself. Here's the deal. I currently have four chicks and will be getting two more on Saturday morning. Their Brooder is an 18"Wx36"Lx12"H plastic rubbermaid type tub. Right now it is perfect. Heat lamp on one end, feed and water on the other and a shoebox in the middle for shade or an area to get out of the direct light. Another member said that I will need to get a larger brooder for the six girls in short order. Question: What do you recommend or what did you use that was larger than the dimensions i listed above? How big does it need to be for comfort? Thought about getting a second tub of the same size/type and joining them side by side and cutting out the walls to effectively double the size. Big enough? Tell me what you all used and most importantly how high so the girls will not jump out of the brooder? Thanks again.
