Hi there fellow chicken folk. We are new to the world of chicken ownership. We have 7 four week old hens in a variety of breeds. We are almost done with building our coop and just in time, our ladies are getting bigger but the min. We have two children ages 6 and 10 months. We all love our chicks, but we also have some concerns about the placement of our new coop. There is only one spot to put it, so we took down our old shed, because it was metal and it gets to about 118 degrees plus in the summer.(we live in southern California) But, the problem lies with our backyard neighbors they have their fence lined with oleander bushes that are higher than our fence. We trim them back but we are concerned about the fluffy seeds that fall over the fence into where the chickens will have their run. We know the leaves and flowers are poisonous, so we're guessing the seeds are too. Does anyone know for sure? Also should we put shavings down in the coop and nesting boxes or hay? And is sand okay for the run area or should we put clean fill dirt in? And is DEFG okay to put on the bottom of the shavings and mixed with the dirt? We know this is a lot but are hoping someone can help us. Thanks in advance.
