Ordered 15 chicks and may grab 3 more as well... Was thinking at first to use a plastic tub and now I'm thinking that may only last me a week? If I cut a hole in two plastic tubs and taped them together would this work? I see 2-2.5 square feet per bird and now am worried that I will have too many for the space I have in our house. We are in a cold weather climate and plan on using an Ecoglow. Temps seem to be trending up so I'm wondering if two tubs could possibly last me until I can get them outside? Advice please! Feeling a bit overwhelmed right now.
