I got some Polish chicks from Meyer Hatchery on May 23th. Two of the chicks died within 48 hours so they offered me a refund so I could replace those two chicks. The next available hatch wasn't until June 13th (3 weeks later), so I ordered 3 new chicks (figured 3 was better than 2)! I completely forgot how fast baby chicks grow and my 3-week old chicks are going to be way bigger than my 1-2 day old chicks. I know they can't go in together right away because the big ones might kill the little ones. So, my current plan is to put a little fence inside my brooder box to keep the bigger chicks away from the smaller chicks but so they can still see each other and get used to each other so I can put them together down the line. BUT, here is my problem. I have an EcoGlow 2 for the heater for the chicks, but I only have one. The new chicks will definitely need the heater, but I don't see a way for the new and old to share. Do the 3-week olds still need the heat? They are inside the house, not outside, and they are all getting their feathers. OR, does anyone have any suggestions on what I can do? I really don't want to use a heat lamp because of how dangerous they are, and I don't want to buy another EcoGlow because they are $80! So, how can I keep both sets of chicks warm and safe?
