finally putting irrigation lines in my front yard. just bought 2 honeysuckles, 1 trumpet vine, 2 privets, 1 creeping orange lantana, bay laurel and 2 hot peppers. already had bought orange common lantana, forsythia and goji berry. can't wait to plant them.
I don't know where you got earwigs from but I know how to get rid of them. if you have chickens that are good foragers (araucana, ameraucana, ee, faverolle, marans, fayoumi. etc) put 2 hens for a couple of hours in your garden. they will take care of them.
I did something similar but it didn't help. I still have 2 sponges and max humidity is 62-63. then it drops to 58-59. I spray through the holes all day long.
judging by the colour. if true partridge boys have 2 colours at hatch and girls 3. I see 2 colours on your chick. girl would have dark brown (almost black) as well. I don't know if your chick is true partridge.
