@yellowherb I was wondering if the glass from using the aquarium is helping with the heat - the only thing I see in your setup that concerns me is the high arch of the pad. For the first few days they like that heat right near them. I understand why you had to do that - can't be easy fitting that frame in an aquarium. First aquarium brooder we've had here on the MHP thread, so I'll be really interested to see what we can learn from your using it. I know that on another brooder thread someone said that the glass held in heat and made it too warm for their chicks, but that was using a heat lamp. Maybe the combination of the glass and smaller space are helping enough with heat that the height of the pad doesn't matter. I dunno, I'm winging it here..... I really like that flap in the front. They seem to get the feeling of scurrying for cover that way, don't you think? I'm really happy that you decided to give this a shot. I don't know why more people don't jump on this bandwagon, because there are just so many benefits. Of course, I have to be totally honest here. I must admit that if I'd heard of this or seen Patrice Lopatin's video and read Beekissed's experiment before my first chicks arrived, I'd have probably shaken my head and thought, "Those fools are going to kill those chicks because they aren't doing it the 'right' way!" @Mims , My Marans started out with nice dark eggs - I could tell them from the others immediately. Not so after they'd laid for a month or so - it's like the dye factory ran dry and there were no replenishments on the horizon. Looks like your little ones have settled in nicely, too! Wyo, good looking setup! After just a few days mine spent more time on top of it or around it than they did under it...sometimes I thought they were just afraid that by going inside they might miss something going on around them. I really love the screen idea!
