I'm getting 30 Silkies this Wednesday and it's going to be really cold around here. I'm thinking of using my tub as a brooder (don't tell dh ) For those of you who've done this: Did you use pine shavings? And if so how did you clean them out once the chicks moved on? If not pine shavings, what other bedding materials would be good in a tub brooder? Thank you!!
