Hi, in our neighborhood we have re-purposed a kids playhouse and sandbox into a community chicken coop. We are starting with 9 chicks. 3 Silkies, 2 Buff Orpington, 2 Rhode Island Red, 2 Bantam Barred Rock. We are going to use tubs for the brooder. I have uploaded a photo of our work in progress coop. And our nesting box we made. Wondering about water nipples for the chicks and also what people are using for dust baths for the chicks if any. Are 3 boxes going to be enough for the 9 of them? Thanks!!!
