Hey all - new chicken owner here. We bought 6 chicks from the local chicken lady since she had the breeds my wife and kids wanted and she could sex them for us. She told us they were between 2-3 weeks old. We have 2 Blue Cochins (1 rooster) and 4 Laced Wyandottes. This was two weeks ago. Well two of the Wyandotte chicks are HUGE now. The one looks as big as a full grown Dove plus shes mostly white. We have another that is about the same size. The Cochins are the smallest but they were the smallest when we brought them home. I think they are all fully feathered, their heads are fluffy and everywhere else is feathered. We got them two weeks ago tomorrow so some should be 4-5 weeks old. Problem is when I turn off the heat lamp (which is just in the corner and the temp is around 80 in the middle of brooder box) they all are fine for an hour and then all huddle together in a pile which means they are cold, right? House is 68 degrees. I cant post photos yet of my chicks but should be able to soon. I would like to get them off the lamp soon and then outside by second week of April. Why then? We are going on a 4 day trip the first week and my in-laws are going to watch the chicks for us. They live next door but it would be far easier to take them in their brooder vs. them coming to our house. We're just paranoid about them getting too cold without the lamp I guess. When I turn it back on they get back up and flutter about and seem to be enjoying themselves! It's just getting crowded in their brooder box (large Rubbermaid) especially with the two big birds. Suggestions?
