Hey all; my chickens are about 10-11 wks old now... I have several that flew the coop today during construction time and I cant get them to get back in the brooder..they are hiding and we are missing 4 of them.. frost warning for the night and its freezing cold out.. we've found almost all of the ones that we couldnt corral today..but we had to leave 7 of them to leave to go to town; thinking that they'd come to the heat lamp we have on the side of the porch and pile of food.. nope..instead 2 went to hide in a bush..we got them.. 1 went in a small tree..we got her... we see one under my porch; cant get to her..she's completely unreachable..but alone...heat lamp is near her but she wont budge... the other 3 are no where to be found... will they be ok overnight w/frost warnings w/no shelter except what they find? ie; bush, plant, etc?? or should I keep looking???
