My BA & ISA chicks hatched on Oct. 27th. They're eating well, drinking well, skittering energetically around in their brooder Tupperware tote & seem toasty warm in their Mama Cave. About half and hour ago, I went in & changed the water in their waterer. It's the kind that uses a canning jar and the water drips into the pan as the chicks drink. I use a 1 pint jar & I filled it full with very warm water...but not HOT. Everyone came over & started happily sipping away at the water so I double-checked that the heating pad was still on at the highest setting, turned the light off & left the room. About 15 min later, I could hear the ladies chirping REALLY loudly...louder than I've ever heard until now. I got concerned that something was wrong or that my cat had slipped into the room without me knowing it, so I went back in. ALL of the chicks were wet to some degree...some more than others...and there was a PILE of them all snugged up against each other and the glass container while sitting IN the water. Do chicks normally water bathe like that? Is this a sign that I'm not keeping them warm enough...or possibly they're TOO warm & are trying to cool off? Should I be concerned with this behavior? I'm paranoid now that the ones that end up on the bottom of this pile are going to drown because the weight of the others on top might push their little beaks under the water. The room is 72 degrees and the heating pad is set on "6", its highest setting.
