We have a brooder that is 6 foot long X 20 inches wide X 18 inches tall. We have two 250 watt red heat bulbs on each side of the brooder and then cool space in the middle. No problems with temp in the brooder. The entire lid hinges up for cleaning and feeding. We have 25 chicks that are now 10 days old. We want to switch from the paper towels to pine shavings now but I am worried about fire. Is it safe to put the shavings in there? Also, any ideas on what to do about the little ones that are growing so fast an learning about their wings....now everytime I open the lid they are trying to fly out. I panic and close the lid. Our brooder is also on legs, about 3 feet off the ground so I am worried that they would have a heck of a fall if they fly out. We are new to this and need lots of help!! All day yesterday the whole family worked on building the coop and hope to have it done this week. This message board is AWESOME I am learning so much, but still need much help!
