This was cooked up by my very handy father and is made out of scrap wood and chicken wire. The floor is black plastic covered with thick layer of shavings. It has hinges hinges on the side allow it to be folded up when not in use which is very convenient! And an Australian Shepherd for flavor, lol.
I went with an expandable play pen. Fully expanded it is a little over 6x3. I have it halfway open since the girls are only 2 days old.
The brooder plate is not the one I originally ordered. The original was sent to TX and will not arrive until March 5th. It is sized for 35 chicks. The one I have now says it is for 20, but they really have to huddle to make it work and there's a bit of squabbling about it.
I added a seedling mat I have to supplement their heat and it covers about 4 extra inches on either side of the plate.
The current temperature in my garage is 65 fahrenheit. The girls do not seem uncomfortable, but I added a light sheet over the side with brooder plate to help keep it comfortable.
Please don't judge me for the horrible gimmick toy, it was an impulse buy.
