So, I have a bunch of mixed breed bantam chicks that are all different ages. It's coming into summer here in Australia, so my 3.5 week olds have been enjoying some time outside most days. I have a few chicks that are just under 2 weeks, and they've been with the smaller 3.5 week olds. Today is going to be rather warm, 34c (93f), and is already 28c (82.5f) in the shade at 10am, so the 3.5 week olds are out already. What I'd like to know is there any issue with putting out the 2 week olds too? Is heat the only concern, or will they be too timid etc.....? It'd be good to get them all out as I had a bunch more bantam xs and australorp xs hatch this morning and would like to do a thorough clean. Also, if the temperature is good outside, I assume it's okay to start leaving the 3.5 week olds outside during the whole day and just give them heat at night? What would happen if it rained and I wasn't there to get them inside? Do they have the sense to seek shelter? They are fairly well feathered but I assume any down is going to make rain a problem if they don't have access to heat. Thanks for reading this and hopefully answering.
